And yet previously unknown companies have announced products with plans to drop those prices further.
That person should be asking you your specific use case, bike placement limitations, and how much you want to spend.
Finally, remember that power meters tend to be about as fiery as politics and religion.
приведенная ссылка keep in mind this is just my view.
There are certainly other views out there all wrong of coursebut this comes from my perspective of trying out all the products below and hearing feedback from literally hundreds of people per day.
Power Meter Placement: Before we start diving into the brands, features and functionality, we should probably talk about placement.
The reason being that unlike a bike computer that works on just about every bike on the planet, power meters actually have more limitations than you might think.
Some limitations are straight technical i.
In either case, for most people this section will help narrow down the selection a bit.
Thus they are more estimations albeit some highly accurate than actual force measurement devices.
Polar chain power meter.
Back to my photo-diagram, I want to expand out the crank area a bit and talk specifically to that.
This is simply measuring and transmitting your total power адрес to a head unit of some type.
ANT+ Support: Another relatively obvious one, the vast majority of power meters on the market today transmit via ANT+ to compatible had units.
This allows you to use one of dozens of different head units out there.
Left Only Power Meters: These power meters only measure power from the left side.
All of these units then simply double the left power and produce total power.
Stages really exploded this category with their left-only power meter, and other vendors followed suit including Garmin Vector SRotor Rotor LT, ROTOR inPOWERand Polar Keo Power Essential.
Note that all bottom-bracket power meters are left-only power.
That platform works by essentially splitting your crank in half and assuming that any power recorded while pulling up is actually coming from the left side, whereas pushing down is from the right side.
And some that have looked into it have found that trying to achieve balance actually lowers your overall output.
Thus why we see it on pedals, as well as the more expensive crank-arm or pedal based power meters.
Polar also has a variant of this in some of their new cycling units as well with their own pedals.
Battery Swapping: All but one unit on the market today SRM supports battery swapping by yourself.
SRM requires you to send it in but gets way longer battery life in between swaps.
The remainder of the units out there today utilize a CR2032 and similar coin-cell batteries.
Most get between 200 and 400 hours of run-time before you simply replace the battery.
However, some of the newer units like the PowerTap P1 that runs on AAA batteries get a bit less time, as do units such as bePRO and WatTeam that use rechargeable batteries using micro-USB cables.
Calibration options: All units on the market today support some sort of calibration function, though to what extent is what differs.
Some have numerous options i.
Quarq with an app allowing you much further accesswhile others are more black-box i.
For the most part, your primary concern here is really that some sort of calibration occurs, and that you can trigger it to happen on demand.
Beyond that it tends to get to more advanced calibration and torque checking methods.
It should be noted that the term calibration can have very specific meanings to different people technically most people are really doing a zero-offset.
They may have slight backorders if you were to order today, but units are shipping to consumers which is where I draw the line.
Note, this list is arranged in no particular order, you can use the sidebar shortcuts to quickly skip to different products.
https://megapixels.ru/100/plenki-zagotovki-dlya-laminirovaniya-komplekt-100-shtuk-dlya-formata-a4-100-mkm-matovaya-531780.html Hub: has been around 15 years — longer than most folks realize actually.
Though their popularity has really grown in the past few years, especially in the US.
This makes it easy to move between bikes, but also makes it difficult if you have separate training and racing wheels — ultimately costing one of those two situations to lose out on power.
And they should have new.
You can make the change back and forth at home in about 3-4 minutes I just did it yesterday for a test ride.
Advantages: Easy install if you buy a wheel set with it pre-installed my recommendation.
Auto-zero while coasting helps keep things in check without you thinking about it.
Manual calibration is easy, and swapping out batteries and the electronics pod quick and straight forward.
Disadvantages: Limited to a single wheel, so training vs racing scenarios can be tough.
Also limited on things like disc wheels.
And if you have multiple bike types where the wheel type changes i.
Versus if a product is simply a slight model change by the same company i.
As for the P1 pedals, they were announced this past spring and started shipping roughly on time this past summer.
Just a simple hex wrench to install and off you go, no settling period required either.
I view the AAA battery as an advantage, though a small group of folks sees it as a disadvantage I love that I can get a replacement anywhere in the world at any tiny little store on a route if need be.
Finally, no pods are on the units — so nothing to worry about breaking easily.
Also the battery life is more limited than some other power meters.
Finally, some folks are seeing odd bike spike numbers i.
Garmin, PowerTap, and ANT+ are all trying to figure it out, as it appears to be a communications snafu rather than a measurement one.
Either way — it sounds to be an easy firmware fix once they implement it.
Would I buy it: Yes.
Relevant Posts:, PowerTap Chainring: At the same time that PowerTap introduced their new P1 pedals this past spring, they also announced a new line — the C1 chainring power meter.
This unit ships with the chainrings, per the pod you can see attached to the chainrings above.
That said, over the summer I used a prototype that generally faired quite well, with the bugs that I saw being known by PowerTap and addressed prior to shipping the production unit.
Disadvantages: Limited chainring compatibility is really the main one, being that the company is only offering certain compatibility options.
Though thus far things look promising.
I kinda put the PowerTap C1, Power2Max and Quarq RIKEN AL all in the same boat: All are great options and all are fairly similar in features and roughly in the same price range — simply go with whatever fits your requirements around compatibility best.
Relevant Posts:Power2Max: Power2Max has been on the scene for roughly a little over 4 years now.
Advantages: The least expensive crank-based solution on the market today.
Solid accuracy with a growing crank set compatibility matrix.
Any temperature compensation concerns are long-gone relics of devices years ago.
Finally, they introduced a Нажмите для продолжения S option, which is a left-only unit that can be upgraded down the road to a complete dual-leg system.
Garmin is the only companywhich includes all assortment of metrics on your pedaling style.
Sometimes these metrics take time for the greater scientific community to figure out how to use.
Unfortunately, Garmin believes that either the system or these metrics warrant a price far higher than it should be.
Garmin needs to reduce their prices — simple as that.
Note on the Vector S system, I generally would just go with Stages unless you have specific plans to upgrade to a full complete dual-sensing Vector set later on.
Otherwise the price there is out of line too.
They announced their first power meter, the bePRO and started shipping basically immediately.
In my testing I found the accuracy was quite good after a few rides to let it settle, посмотреть еще from that point forward it handled fairly well.
Advantages: Price — the unit is 749EUR for a dual-leg system or 499EUR for a single-leg system.
Accuracy seems to be pretty good too.
Disadvantages: Installation can be kinda finicky at first, and you do need to take their special tools with you if you travel.
Finally, Polar announced a new version last summer, Keo Power Essential, which is a left-only option.
In this scenario you just get the left pod and pedal, and then it doubles the power for the right side.
This has the same inherent limitations as Stages, but also offers a lower price point than the full Keo dual-pedal system.
Appears accurate, but really hard to validate all aspects i.
Disadvantages: Installation is a bit complex.
Not as easy as Vector to move between bikes.
Would I buy it: Definitely not.
Relevant Review:, Quarq SRAM : became the first non-SRM crank-based power meter that was actually affordable.
The unit replaces your existing crank spider МФУ Epson EcoTank ET-7700 depending on the model is typically sold with specific crank arms attached.
All Quarq power meters are made in South Dakota USalong with servicing and shipping from there.
The Quarq Cinqo was actually the first power meter I bought, and what The Girl subsequently purchased as well for her training.
Since then they introduced their ELSA unit, which also includes the same technology.
RIKEN was also introduced at the same time as a replacement for the older generation Cinqo units.
This past spring Quarq dropped prices again and introduced their Quarq RIKEN AL option, which is a pretty solid deal.
Advantages: Crank-based design means no wheel swap issues.
Accuracy on-par with other units.
Can swap chain rings without issue.
Easy replacement of battery, and can utilize phone apps for further calibration.
Disadvantages: Crank arm selection has diminished some with SRAM acquisition reducing compatibilityand while Spring 2015 pricing updates has made things substantially more competitive, they are still on the higher end of the sale between Power2Max, PowerTap C1, and themselves.
All of those units perform as expected technically.
Relevant Reviews:,Stages Power: Stages continues to press forward and expand their lineup, most notably over the last 45 days with the addition of carbon crank offerings and re-doing their pod design, which should help with waterproofing issues they saw.
And of course, continuing to sponsor Team Sky.
It simply doubles the left-leg power to get total power.
This means if you vary, or vary in certain conditions then the power might not be accurate жмите сюда or something that you could compare to years from now on different products.
They were also the first one to do dual ANT+ and Bluetooth Smart dual broadcasting.
Contains both Bluetooth Smart and ANT+ and dual-broadcasts.
Disadvantages: Left-only approach means simply doubling left-leg power, may not be fully accurate representation of your power high or lower.
Would I buy it: This is a much more complex question.
However for longer or higher intensity rides where I might fatigue more, I see some inaccuracies on Stages due to my personal leg differences.
You might be the same, or you might be perfectly even.
They announced a year ago at Interbike and started shipping this past winter.
Their solution is a small pod that could be self-installed onto your own crank arms.
While the self-install piece is currently on hold, they are doing installation on your crank arms through the mail.
So in many ways the product today is like Stages, just cheaper and whereby you can use your own cranks instead of having to purchase new cranks.
Can be applied to most cranks non-carbon.
Contains both Bluetooth Smart and ANT+ and dual-broadcasts.
Disadvantages: Left-only approach means simply doubling left-leg power, may not be fully accurate representation of your power high or lower.
Would I buy it: Potentially.
I had some initial accuracy problems with it on the first units they sent me, due to some aspect of my pedaling technique.
From a power meter standpoint however, they are really just as susceptible as any other power meter on the market to adverse читать />Which is probably an important point to note: No power meter out there today is perfect.
They all have conditions where they do really well, and conditions where they do less well.
Many of the products in this post can produce just as consistently accurate power as SRM which again, SRM is good at doing.
The reliability is generally very good.
If looking at their head unit not requiredthe current generation is simply really expensive for what you get.
Relevant Posts:,Pioneer Power Pioneer has iterated nicely through two generations of power meters over the last two years, roughly paced at one per year.
They also released a second edition of their head unit and have added some nice incremental features over the past year.
And finally, they got busy with pushing out a left-only product line that can also be upgraded to a dual-leg system later.
While the 1st generation units received a bunch of undesirable attention due to ziptie usage, the 2nd generation units removed that requirement.
It also removed the complex-crazy installation process by going with a process that you ship them your stuff.
The unit has two modes, one for ANT+ and one for private-ANT enabling the higher-analytic pieces noted above.
To get that additional data you do need to use their head unit, which while strongly suited for its specific pairing to the power meter, is overall under-featured compared to something like a Garmin Edge.
A completely pre-set system once it arrives to you.
There can be a small delay when you send away your own cranks to get it installed versus buying a pre-installed set.
Relevant Posts:, Verve Infocrank Verve introduced their Infocrank power meter last year, and continues to chug along with incremental updates to the platform and hardware options.
This dual crank-based power meter has strain gauges on both crank arms.
Additionally of note is that the unit has custom designed crank arms that are specific to Infocrank.
The unit transmits on ANT+, and uses small coin cell-style batteries that you can go ahead and replace as required no sending in needed.
Of course, at the same time, most other power meters are fairly accurate as well — but Infocrank seems to be more hassle-free when it comes to that piece of things.
Though the lack of requirement to occasionally manually zero is handy and low-maintenance.
Relevant Posts:ROTOR: has been in the power meter market about three years now, and iterated through three different products in that time.
However despite my trying it quite a bit, I never got the system to accurately display power for me.
Ultimately I can neither recommend it nor not recommend it.
ROTOR then shipped a left-only unit, the LT lineup, which ostensibly sidestepped the accuracy issues since being left-only sorta negates some elements of accuracy.
Finally, last summer they came out with theirwhich measures power at the bottom bracket, and is also left-only.
узнать больше Compatibility with ROTOR cranks and elliptical chainrings.
Of course, until they do release a final product things could change.
Ones that look promising could flop, and others that have challenges could be superstars.
Not SRM new rechargeable modelnot Garmin Vectornor Polar Bluetooth edition.
The system is planned to work on both carbon and aluminum cranks, and is a bit less dependent on the flat surface of the back of the crank arm like 4iiii Precision.
This past July I had the chance to spend a week riding the system, and came away fairly satisfied with where things stood.
They started accepting pre-orders a month ago, and plan to ship in December updated date.
I think this is definitely a unit to watch going into 2016.
Related Posts:, Brim Brothers Zone: Next up is Brim Brothers Zone, I previewed them a year ago at Interibke.
The Zone system is cleat-based, and attaches to the base of your Speedplay compatible cycling shoes.
This is ideal for those with numerous bikes, or who travel 300 FC1030INOX Лоток 100 DKC мм проволочный х 3000 кабельный х can control the pedal type.
During my preview I ran into some snags, and that in conjunction with a few other items caused them to delay shipping to work on this.
These MIT students have the foundation for a potential power meter company and product, and were able to demonstrate it to me both indoors and outdoors.
They also have riders on one of the local teams testing out basic prototypes of the platform.
Note that the solution will be limited to measuring left-only power.
Dyno Velo: I visited these.
Their pricing will likely be in the same ballpark as the Ashton Instruments option and targeting the same customers.
LIMITS Power: LIMITS as part of an Indiegogo campaign.
The unit sits in between your pedals and your crank arm, offering near unlimited compatibility.
I e-mailed them again this past weekend on where things stand as part of an upcoming post and hope to get further clarity.
XPEDO THRUST E: Next we have the perennial party crasher at bike events worldwide, the Xpedo Thrust E.
Astoundingly, this year they actually said March 2016 — as opposed to 3 months away.
Luck Shoe Power: This one slipped last year as the first shoe-based power meter.
The power meter sits inside the bottom of the shoe, and will transmit over Bluetooth.
Non-DFPM Devices: Finally, we have a few options that use calculations and black magic to determine your power output.
Thus the name of non-Direct Force Power Meters DFPM.
PowerPod: I tested this back at.
The unit attaches to your handlebars using a standard GoPro mount perfectand then measures wind speed, acceleration, and incline to determine power.
In my testing, it was fairly accurate in normal conditions i.
Of course, that was limited testing on a prototype system, as the pods plan to ship a bit later this year.
PowerCal: The offered in both ANT+ and Bluetooth Smart is a heart-rate strap that also transmits power information.
It monitors your heart rate and then uses the rate of change to determine power.
My challenge with the iBike has primarily been the head unit side, and not the power meter side.
Compared to the power meters of today, the head unit is just horribly dated.
But I think the company is on the right track with the PowerPod and focusing on a solo power meter rather than the full package.
A Quick Note About Buying Used Power Meters: Everything in this post is talking about new units whereby you are the original owner.
In that case you would know if your friend was having issues with it, and the reason behind the sale new wheels.
In most cases, the best 3rd party to complete that test is the manufacture itself.
So What Should You Buy?
Placement will drive usage i.
The landscape will continue to change.
Nothing new will hit on the market until then, and thus companies have no reason to shift prices based on speculation of other units.

Notify me of followup comments via жмите сюда />You can Wow — really great write-up, especially for someone like myself who was literally waiting on exactly this recap to make a PM decision.
One point — I realize that prices may vary, but for me at least it would be a little easier to read if approximate pricing was included inline.
Some reviews Stages, for example include it, but others such as the G3 do not.
I usually include a link to the product comparison tool for power meters, but I know the pricing there is slight behind right now.
It get super tricky too with all the variants, so I usually aim for th cheapest offering and go from there.
What you you recommend?
Under unreleased products the last sentence in the first paragraph says.
I guess that might your judgement a little bit less clear cut, no?
Yeah, it gets super messy when countries vary so much.
So I tend to focus on USD pricing as it generally works out the same elsewhere, but there are some odd exceptions.
To be fair, Garmin is on sale but might be permanent price нажмите сюда />In any case PowerTap seems to be expensive in Europe.
Same here for Switzerland.
The P1 I would find more simpatico because of integrated podbut they are not available.
I would need to buy them from an onlineshop, but they would more expensive than the Vector 2.
Been a Vector owner since they came out, to be honest my advice would be to stay clear.
I think the P1 is a nailed design, the Vectors seem to be finicky at best.
Forums are full of posts from people experiencing significant problems with the pedals as the spindle starts to develop unacceptable play.
I myself also experienced this problem and would definitely like to hear if other pedal power meters show a better result here.
Garmin quietly made a crapton of mechanical changed in the first 12-14 moths of Vector, almost all of which went unannounced.
These were primarily aimed at items noted in the forums.
To date they continue to basically swap out any units for newer ones no questions asked.
I get the feeling that the main drive behind Vector2 was honestly just to press a virtual reset button on it so people would realize those changes were made.
As otherwise there are almost no changes between a late stage Vector1 and a Vector2.
Is there any way to tell which version of the Vector 1one has?
Maybe an update of the article would be fair?
Really dig the pricepoint of the P2M and the C1s now, but wish the P2Ms offered BLE flexibility.
ANT+ if all higher end devices 800, 1000, 910, 920 are ANT+ compatible?
Getting a new bike on Friday, so you timing is epic.
Dual Ant+ and Bluetooth was a big difference.
Half the difference in price is swallowed by not having to buy new pedals.
What is your position on giving the user a straight forward means to verify calibration slope of the unit?
Vectorit becomes more difficult.
Vector solves that by giving you slope at a given point, which helps a bit though.
I think that having some way to validate something is drifting such as an offset value is pretty important overall.
Plotting the data on to a graph, should make it fairly easy to see if it shows an even and centred circle.
Hanging a weight of the tip of the pedal, would also be an easier and probably more accurate way of setting the install angle.
I move my vector often, and find it a bit tricky to do the 80ish rpm with some load in busy city streets.
Hi Ray, great article and one question — do you have a short list of power meters for a mountain bike?
They are actually kinda different.
Pioneer more heavily focuses on higher speed measurement and pedal force area.
Actually, Pioneer now also includes some of the better known metrics from Training Peaks in their latest firmware, as seen here:.
Having tried a few across the last many years, this one has been the most routine, provides great insights, and appropriate to daily use.
Meaning, no association with pedaling.
And finally, no dependence on Pioneer pedals for that, any power meter works there.
He showed data to back his rationale.
He was big on infocrank, garmin double side, and PT pedals.
Pioneer too, but their software is not compatible with the trainingpeaks software suite.
We also have an issue with pedal spindles of varying lengths e.
Clearly this is an evolving market and they are getting closer.
Still have room to develop the products to the needs of all riders, but there is definitely value to be had for the vast majority.
However, the real picky folks are likely to have some issues choosing.
Wellgo manufactures the cleats for the Powertap P1.
So, if you can find Wellgo cleats locally, then they will be much less expensive than buying from Powertap.
I look forward to this post r.
I had a Stages, and after looking at data more and more, it was just inconsistent, because so am I it turns out.
So my Stages went back, and I truly believe that they are doing a disservice to the industry with this left-only approach.
While they initially allowed people to get affordable power meters, they did so at the expense of issues mentioned above.
Today I cannot recommend Stages or any left-only power meter to anyone, especially as there are comparable priced meters that can capture total power.
Great review as usual.
Anxiously awaiting your thoughts later this week on 4iiii.
Looking at the 4iii right crank arm prototype Ray had on this site several months ago, i think you will need it.
I race track velodrome and typically use a different chainring for warmup and the actual training sets and maybe back to the first for warmdown.
If its a five minute job, that you do each time you change the battery 1-2 months?
But, CX1 uses a standard Force carbon crankset, not a mtb one whatever that means.
So where does this leave those of us that were early adopters of Vector?
Is the only issue you have with Vector the price, or do you feel that the P1s are a better product altogether?
I think pretty much all of the component manufactures will get into the game.
Eventually power meters will be like dial-tone — everyone has it and nobody cares how it got there.
Tiny typo — you missed the P1s off the pedal based meters on the list under the bike anatomy photo.
Thanks for an awesome summary!
I think they believed no one was going to come out with a pedal or cleat based system that could compete with their unique offering but PowerTap did and I trust their accuracy more.
Have travelled with them and used on other bikes, and just so easy — perform a zero-offset on the garmin and ride.
What you really need with a power metre is repeatability.
Once you realise this cheaper options become much more viable.
Any meter that gives repeatable data is great.
Those that have vary over time or require recalibration kinda defeat the whole objective.
And if that unit is skewed then all your past history goes out the window.
Even if the past is just last week.
Additionally, if a unit is precise then generally speaking it should be fairly simple to also make it accurate.
Thanks for putting this together, Ray!
Was the extra few % power I could sustain because I got fitter, or because I switched from on power meter to the other?
I forgot to run a few tests with both PMs at the same time to be able to compare, so I never found out.
Ray: do you have any data on Vector узнать больше здесь from 4 to installation?
I always travel with my torque wrench, and always install to the same torque as close as I can anyway.
Flobble- I find the consistency from installation to installation good, assuming you give it a day or two and then assuming you do all the steps to reset after a short sprints and torque correctly.
Hi Ray, Been waiting for this post for weeks!
Thank you so much.
I was hoping this guide would include where you think prices are going and when but it seems not.
I will definitely be purchasing them from clever training though!!
Actually he has mentioned in recent power meter post price reductions are likely March 2016 then again end of 2016.
Pretty standard for this stuff.
You can always wait and get it cheaper…or just get it now and move on.
Arron, Do you know where the post is exactly?
Or someone like Garmin could decide to throw down and trigger a price slide.
Excellent review as always — whats behind the relatively high prices of some of these units?
Difficult to manufacture or are they just trying to get as much as they can?
I would think there would be a huge market for them.
Do you know anything about the new RPM2, an insole based solution that comes in running and cycling variants?
Looking at the powerbeat website at preorder, it shows the system is only hollow alloy compatitble.
It also asks you to choose your cranktype before continuing.
Does this mean they system is different for different cranktypes?
Hi there, great article — incredibly thorough!
It seems that the pedal based or hub based systems are the only options as most of the other systems only work on alloy cranks?
You could always use Athena cranks….
Chainring compatibility is a ссылка на страницу better than most people seem to think.
Previously was using 2009 Chorus, and in early 2015 replaced it with the redesigned 2015 Chorus, and the Quarq worked fine on both.
I installed WickWerks rings and think they are the equal of Campy Надеждина Вера 100 великих идей и книг, которые помогут вам изменить жизнь к лучшему />I previous used Stronglight replacements on a Campy Chorus crank, and found the Stronglights very good.
I was going after a Stage.
Especially when I heard about the last price drops.
Also, I feel fatigued after certain time of riding.
Thank you for making this an easier choice!!
I always enjoy your yearly guides.
The P1s look like a great solution though, and could certainly be my next purchase if I replace my Vectors.
I hear that their cleats and the pedal fit with standard Keo cleats is a bit of a problem though.
Do you know if they will be looking to change this?
I e-mailed them a 4 of questions Friday night, and then we traded e-mails two days ago, waiting for another response just смотрите подробнее to poke them again.
Thanks Ray, have been waiting for this to come out — but, as expected, your guide has given me the confidence I needed to buy an SRM.
Perhaps 5-7 years ago, but not today.
I chose limits due to price and ability to easily swap over onto another bike, as I use different shoes with different cleat systems.
To me this explains their excitement with enabling ota software updates in an update a couple of weeks ago and confidence that they can ship in 2015.
Not ideal but seems like this happens a lot with crowdfunded tech, just hope this approach will help them get the accuracy sooner rather than later.
And stages, pioneer are all cheaper than buying 2 hubs Ok, compared to SRM and ROTOR maybe this is true, but not with the other solutions.
Or maybe I misunderstood what you were saying?
Ray the RPM2 web site home page says Ant+ and FIT comparable….
I just talked to RPM2 at IM Kona and they say they now transmit on ANT+ and are within 7-10% accuracy compared to other power meters.
It is a medical device aimed at physical therapy and will give you range of motion at hip and knee.
But it will still be an orthotic device with measurement and not something designed to fit in normal athletic shoes.
The technology looks really promising.
Just put them in any shoe used for any bicycle or run, but they seem determined to produce a tapered orthotic pad which will require special shoes.
I hope someone else picks up on the idea and builds something appropriate for athletes.
A quarter million dollars to make molds with FDA stamps on them is preposterous.
The sensors and brain are only 2-3mm thick.
At 1st I thought this was a good idea, but after thinking about it, I am not so sure.
I have to replace my current insole about every year as they totally fall apart….
I will admit that my current insoles are just lame, but that is what works for me : and I have tried most of other options.
C The power meter that makes the most sense to my circumstances multiple bikes and firmly committed to Speedplay pedals, even if I travel would be Brim Brothers product.
Technically I expect they will crack it.
To recoup that they are going to have to either sell a lot of them or charge a premium for them.
If they go the sell cheap, sell lots route, then they will be competing by the time they are in the market with some pretty cheap and getting cheaper existing meters by then, plus they have limited their market size by the meter being Speedplay only.
On the other hand, a premium price only makes sense for those people who would definitely otherwise be buying more than one meter for their multiple bikes and calculate that its cheaper to buy one Brim Brothers product than it is to buy 2 or 3 separate power meters.
I really hope they succeed and 4 my perspective, hopefully with a relatively cheap product but I struggle to see how they are going to get the pricing right to reward them for their years of endeavour.
I hope I am proved wrong.
One minor enhancement might include the information transmitted.
That may not be worth much to many people, but not having to deal with alignment is pretty convenient.
Almost all the powermeters on the market now provide cadence.
In fact, a bike computer like Garmin will ignore your separate cadence sensor and use the one provided by the powermeter.
So in short this behaviour of using the PM number rather than the Cad sensor is desirable.
The hub based cadence is less accurate than sensor based, and ususally head units will use the sensor-based cadence in preference, as the headunit knows its a hub-based powermeter it has to to decode the readings.
But in reality, the only measure one side, I am right?
As far as I have understood, Power2Max only measure one side and has a kind of algorithm that try to stimate how much was on the left and right side.
Actually, this algorithm try to do something to see when you are not pulling with the right side and estimate the left-side.
For instance, INpower also do this: although INpower does not give you an estimation of both side only measure left and duplicate in the software I think you can study you effectiveness and other variables, and for instance you can see when you are pulling and when you are not pulling during the pedal circle, but they just not implemented this algorithm to estimate the power when you are not pulling.
In conclusion, you can not say that it captures all power when it capture power in one side and estimate the other side.
Power2max captures all power…it is measuring at the interface between the crank arm spider and the chainrings.
It is unable to empirically differentiate between right and left side power.
Power2max is composed by one powermeter, it measure on one side… but futhermore, if it does that, estimating 12:00 to 6:00 as the right leg and viceversa, something is wrong too, because you can aplied some effort before 12:00 and after 6:00 Abraham: Ray is still correct.
Power2Max PM, like Quarq PMs, captures all power.
This is completely different from a left crank arm only powermeters like Stages, which doubles the measured power from the left crank arm.
P2M is measuring the power that goes перейти your cranks which are attached together into your chain, at the point just before it reaches the chain you only have a chain on the RHS of your bike right??
Try unclipping your right foot and see if the power from your left foot only causes there to be tension in your chain….
For a Shimano user, that is a glaring omission.
And why would you say that the ability to turn off auto-zero is only for the most advanced of advanced users?
A bad auto-zero can cause issues for everyone — period.
If I tried to list every crank, chainring, bottom bracket, wheel, or other incompatibility it would be impossible.
As for auto zero, hardly.
The number of inaccuracies people get would be взято отсюда smaller than with keeping it on like 100 to 1.
True, but Shimano cranks are pretty popular I would say.
And I bring it up because you mentioned limited crank compatibility with the Quarqs, so just in terms of fair play.
We can choose to disagree regarding auto-zero.
And I would think every user would want good data, regardless of their cycling ability.
I would agree that those that turn it off may have more inaccurate data, but I would bet only because they forget to do a manual-zero 10-15min after the bike has acclimated to the temp outside, before their ride.
If this act qualifies one as a most advanced of advanced users, then so be it.
And if people forget to do a manual-zero in 20-30 degree temp swings, so be it again.
How does the 4 work out on a large climb, where it cannot take place as you cannot coast or backpedal?
Temperature compensation seems like a band-aid over a bad design or materials used.
Some meters are better designed and less susceptible to temp swings in terms of torque offset.
Still, a manual-zero should be something everyone with a power meter does — auto-zero on or off.
Curious what happened at the ANT+ Symposium.
Was there any discussion of manufacturers sending the zeros to the head unit for looking at later?
This would be easy I would think to implement, and would be good data trail to have.
Virtually all power meters using some form of temp compensation — either active or passive.
Not sure on PM companies sending zeros to head units, I keep asking for it.
Look at the cranks which SRM uses for their durace series powermeter.
It is a specific off series crank with a removable spider.
The issue lies with shimano.
I understand the reason.
Like you Ray I have a marked imbalance between left and right making pedal PMs the best option.
If I could afford the Powertap P1s I would get them, but they are very expensive in Europe certainly not a direct currency exchange rate and so I shall be opting for the bePROs.
Thanks as always for your informed and as much as is humanly possible impartial advice.
While I appreciate that sales tax is state based an often worthless.
I now want them all!!
Here is my take, based on my own personal expereince: I have LOOK KEO POWER on one bike, SRAM QUARK ELSA on the second, Vector 1 and 2 on the third and PowerTap P1 pedals on the fourth.
I bought them as they came out, starting 4 or 5 years ago with the LOOK KEO POWER.
They all work and all have their quirks.
Really only Quarq, Power2max and now Stages custom carbon crank.
BB30 without adapter only cuts out a couple of options… No Pioneer.
Clearly you can get any pedal or hub based option.
If your cranks are compact you can get Powertap C1.
Check up but i think that infocrank has a 30mm axle option.
It is only pioneer that is not an option.
Great article, I would probably add weight as a disadvantage of the powertap hub system, beyond being limited to one wheel.
For my 5+ year old SL2.
Besides the whole one-sided argument s.
Appreciate you weighing in Tim.
It really is so fast to move between bikes, its quicker to move a wheel from one frame to another than to change even one pedal.
And no need to re-calibrate as it does that every time you coast.
Great article as usual, thanks.
Michael, would you mind providing the name of the German company you purchased your InPower crank arm from and their web address?
I am thinking about replacing my left Rotor crank arm as well.
Are the pre-orders coming out slowly, or is there just not a lot of buzz about the product?
I think most times buzz happens when the right people get something as in, people who happen to post online.
In this case, might just not have fallen into whatever hands those would be.
They have also improved on their customer service.
I have gotten answers within hours of emailing them — I think BrimBrothers should just sell their concept to Speedplay.
I loved their concept when they announced it but it had dragged for about 2 yrs now?
Yup, I do plan to review the PowerPod beyond my initial post, once a finalish unit is available.
As for pro teams, as I noted above — they are sorta meaningless when a sponsorship fee is paid.
I paid a very good price on my Rotor 3D both legs measured bought in Asia, I have a G3 to compare and the numbers are spot on, I am happy with it.
I use them with oval rings and I like to see the slight changes in the metrics when playing around with the MAS system.
Great write up, thanks.
One important point about Pioneer — is it easily available within Europe?
Through their website the availability within Europe seems to be limited to: Belgium, Luxembourg, Nederland, Italy, Germany, Austria.
Seems… lacking, to say the least.
As an owner and user of Quarq, SRM and Power2Max power meters, I would like to add a comment on the SRM meters.
They are definitely reliable and accurate although not noticeably better than the Quarq or P2Mand SRM has great customer service in the US.
That said, in addition to falling behind on price and user serviceable batteries, they are also behind on installation.
The SRM does not have accelerometer based cadence and requires the use of a magnet.
While this is not a big deal on most frames, mounting a magnet in a good location can be very difficult for some frames.
Even with good adhesives, the magnets tend to come off periodically, leaving you without data for your ride.
It is still on Indigogo project fase but you with all your contacts and knowledge may want to look into it.
If you have 4 allready done that allthough I have never heard anything about it on the site.
I guess I'm back to the Stages option.
Can you still get the Classic?
Checking on the German and US websites it seems sold out.
This leaves the Type S which is a more expensive product.
As usual fantastic write up.
Thank you so much for putting this out.
I have a quick question for you.
Any way to buy it in a way that gives you credit?
So within that, they only sell direct to consumers.
But others have done comparisons and shown no issues.
So unsure how many it really impacts.
As for your situation, I do agree with your summary.
I think the ordering lead time is a bit longer last Https://megapixels.ru/100/igrushka-zvezda-svetitsya-v-temnote-22-h-18-h-5-sm.html heard was 6-8 weeksbut I also heard that Clever Training has some units that either just arrived or are on the way.
Reading it makes me wonder like Щипцы Atlanta ATH-6670 remarkable the market becomes over-crowded?
I am a gear guy and a have been training with power 2 trsuty powertaps since 2010 and have been looking to make a change so it is easier to swap wheels, trainer power, etc and gain power on my MTB.
Your prior article made it clear to get in line for the P1s which I did.
Reading this one today, made me realize that I should build one of my PTs into my MTB wheel.
Do you think I could use garmin vector on a mountain bike during marathon https://megapixels.ru/100/papka-faylovaya-na-100-faylov-krasnaya.html or dust, mud, etc.
Powertap G3 help: This morning I swapped out the batter on my G3 hub, and since doing that it seems to no longer be working.
I have tried a couple different batteries but no luck.
I did notice that the replacement battery do not seem to be sitting as tightly in the slot.
The hub just turned two and this is the first time I have had any issues with it.
Any help would be greatly appreciated.
One area I still am confused about is head units.
That said, if you do suffer an injury, it can be useful to follow the state of recovery.
As for head units, generally speaking most Garmin cycling units support all power metrics for ANT+ units.
When it comes to Suunto, they support жмите power ANT+ on Ambit2, Bluetooth Smart on Ambit3.
They add support in one firmware update and break it in the next.
Hi Ray, Sorry for my once and for all question in advance.
Retesting my FTP every quarter becomes a pointless exercise unless the result is accurate as it will change all of my training levels.
I suppose the question I must ask is that regardless of cost, which unit do you believe to give the truest read-outs, as frequently as possible?
Thanks, Jess I believe SRM is the best, although I know Ray will disagree.
See publications from AIS, etc.
Yes, very pricey, but still the king.
It would be cool if you used ZWIFT to compare some PMs.
However, in ZWIFT it dictates how fast you are in a competitive environment.
Personally, I have run 2 crank based PMs withholding Brand names in ZWIFT.
You are referenced quite a bit on the ZWIFT Riders FB page so I am sure they would appreciate it.
A lot of unqualified recommendations are going on there right now as everyone is getting ready for the BETA testing to end.
Kudos to Garmin support for the great feedback and keeping us posted in their support forum.
Do they increase the Q-factor horizontal distance between pedals?
It looks like the Limits system does massively.
Personally I think I would find it hard to adapt to an increased Q-factor, especially if there was a difference between my bikes.
As I understand it, most cranksets as they stand have a larger than biomechanically ideal Q-factor, so not great to be increasing further.
Aerodynamics would also be compromised.
For somebody looking to purchase their first PM- what would you recommend.
I think with this annual post it would be a good idea to group and rank them according to their respective category.
I feel like you very easily could rank them within their respective categories ie.
Great reviews and leads me to wonder if anyone 4 collating a study of variation between the power outputs of each leg where the owners are measuring both sides such as with the Vectors?
I reckon with this amount of data getting uploaded there must be a huge amount of big data available on these variations.
Now if Garmin could use this for follow up features where they contact riders who their analysis shows have permanently fixed this imbalance and ask them to provide their training routines for everyone else to benefit from.
It would be a good way to find out what routines work in the real world amongst every day cyclists.
Who knows — it could be pedalling drills, it could be osteopathy adjustments to the knee or hip or it could be strength exercises 4 the bike.
In fact, the very little mostly non-scientific research out there shows that people who try and correct it end up with a lower total wattage.
But I do agree that Garmin has done little nothing insofar as making research into this easy.
That pool of data would go a massive way towards study in the area.
You can select a large list of trainers, modify the given power curve and also works with different wheel sizes.
It has a Lite version only works for 20 min and a paid version for a couple of bucks.
The only downside is it can overestimate your real power for the first 10 minutes until the fluid trainer warms up.
Hi Ray, Perhaps you can leave a paragragh in your guide for a commentary on power meter choice for tandem riders.
I have a Canondale Street Tandem and I would like to know what are the options that i have?
But what about powertap, left crank, spider based power compatibility?
Im in a fix getting a power meter for my tandem and I prefer Shimabo pedals.
But I do not know whether there are the other possibilities.
Have you ever run multiple systems on the same bike at the same time and compared outputs?
Yup, in fact, virtually every ride I do is with 3-4 power meters at once.
Doing a PM review with only one power meter is simply called marketing.
For me, crank based is where it´s at.
Powertap works great but most of us want to change wheels, race TT with discs, etc.
Pedals just seem to disposable for me to pay for a power meter on.
For some reason, I don´t mind that my expensive carbon bike was made in Taiwan, but I like that my power meter was made in the US even if the parts are sourced overseas.
Quarq is made in South Dakota and Stages is made in Colorado.
I´ve used both these meters and made use of both companies customer service and both have been top notch.
I know a lot of local racers, several of whom have national hardware, train and race exclusively on Stages and despite the junk posted on Slowtwitch, unless you have some strange medical situation, it IS good enough for you.
Personally, I have two quarqs right now and I think the best power meter for the money is a quarq elsa ~1100 on amazon prime with dura-ace rings.
Second best is a dura-ace 9000 with Stages.
For some reason, I think Stages will be able to drop their price to point where a power meter is not a boutique piece of equipment, which it still is, unfortunately.
Then they might be my top choice.
I´ve heard some good things about power2max.
I wouldn´t seriously consider anything else posted on this page.
The most important thing for me is accuracy, and price.
Even tough I like de Power tap pedals, they are very expensive, and I would have to change my speedplay pedals.
Theres a little problem with my rotor crank, because If I just buy the powermeter, I would have to send it to rotor, for them to install the power2max, so I will have to pay the mail costs.
Ill buy power2max with new cranks and thats it.
Is there any product out there which displays torque and not only the derived power value in Watts.
I am interested in seeing how strong I push the pedals.
However what I am looking for is realtime data.
I believe this would be really useful for several purposes, eg like optimizing saddle position, or optimizing my position, optimizing pedalingmeasuring improvement of leg strength etc.
A workaround would be to ride at a constant cadence and compare Watts.
It seems strange to me that obviously most or all?
For example the issues that people were having not being able to set the crank length with their P1s.
Do the p1s transmit cadence and torque which then is used by the head unit in combination with crank length to show power?
You could get sort of real time torque data by using the zero for your power meter.
Do a true zero with no load and write down the counts reported.
Then put a known weight on and redo the zero, recording the counts.
These two points allow you to calculate ссылка на страницу scale factor between counts and torque.
As your pedaling you can repeatedly zero the meter and look at the reported value.
Kind of a pain but maybe good enough for your purposes.
I only have one bike, a Giant TCR Composite 2014 with Ultegra 6800, a Shimano Press Fit BB and SPD-SL pedals.
Cost is the main factor here, swiftly followed by consistency and accuracy as the most important.
Any advice would be gratefully received!
I appreciate all the time you spend to give us some more perspective on all of the triathlon gadgets!
I sent it back and Stages was very quick to help and remedy the problems.
I also took advantage of the recent discount on the 920XT!
After a few minutes of googling, it looks like many people have had problems specifically with Stages connecting to the 920XT.
Definitely not something systematic that I hear of.
Part of it is really placement, especially on a triathlon bike while riding.
But pairing is super-odd.
Hi DC In the UK we are now seeing the Garmin Vector 2s on offer £100 cheaper than the Powertap P1s.
I адрес at what sort of price differential you would choose the Garmins?
Keep in mind, the 2S is just a left-only power meter, whereas the P1 is a dual left and right pedaled power meter.
Powertap seems overpriced here in the UK.
The new vector 2 seem easier to mount with less issues than previously, but would it be better to pay the extra £100 and have the simplicity and what seems very easy to mount power taps.
Looks like the cheap offers have gone.
Evans has no Garmin Vectors showing at all, only spares and Wiggle is back over £1,100.
There are still a couple of online sites I have never heard of showing below £900.
I see that Wiggle is out of P1s quoting 2-4 weeks This is a great source of information, so thank you Ray.
I am new to triathlons and cycling in general and want to learn more about power meters before making the investment.
Is there a good resource to look to find what should be important to my needs?
Are there any further developments with the 4iii precision, in terms of a more thorough longer term review?
Yup, coming up over the next few days In-depth review.
You can actually see little tidbits of it, in my PowerTap C1 review that came out yesterday.
Hi Ray, I know that it is completely dependent on a multitude of factors but, just out of pure curiosity: If you had one bike, money was no object, and you could only pick one powermeter, which one would it be and why?
Just was wondering, from a completely subjective standpoint, which was your favorite… Trying to get my wits wrapped around all this data without the benefit of any prior experience.
My question: are all these Vector fields common to ANY ANT + — compliant power meter?
I would like to purchase PM.
And here is my question.
I have SRAM CX1 transmission, 1×11, 46t or 48t or 50t in the front and 11-36t in the rear.
I use SRAM X-Sync chainrings, my spider is 5 bolts BCD 110mm.
What PMs would 4 in my case?
One of our co-worker ride the same system without any problem.
I looked at P2M, but my bike is a Trek with a BB90 bottom bracket shell and would require, at the least, changing chain rings.
Stages just keeps coming up as an affordable, simple and easy option Шлюз VoIP Yeastar TA 100 me.
Keep us posted on how it goes.
Pedals are also good and reasonable place to measure power.
I think Stages is still the next most-viable option for me…only!
I think your in Europe??
STP Thanks for the great and comprehensive write-up.
Learned much more than I started with.
Thanks in advance for the insight.
Or any of the dual-leg capable units.
Just my two cents.
I ran a Pioneer Dura Ace 9000 unit on my Cervelo P5 last year.
I источник this by shimming the spindle quite substantially, increasing stance width about 5.
Interested in your thoughts on whether other crank based meters would clear the BB and stays on the P5.
Hi Ray, What would be your recommendation — I am looking for a Power meter that I can easily swap between my training bike and my TT bike.
Are the PowerTap Pedals my best option?
Is there something similar in the market but… cheaper?
Thanks for your great review!
Whats the best value that I could get on a student budget thats still accurate enough to compare to other people i.
If they could actually improve it to the point where it really is as accurate as anything else, it certainly has all kinds of advantages over just about anything else as far as portability and ease of use goes.
Been following your website for a long while, especially interested in the PM talk and whatnot.
Continued checking the C1 and the Riken AL as my viable options, and it turns out that the C1 is not compatible with my SL-K BB30 crank the spindle is shorter or something.
I may be missing something fundamental….
Questions about the BASICS of power meters and smart trainers.
Although the focus of this thread seems to be more on the ins-and-outs of actually using the power meter data to train, it seems about as appropriate as any place I can find on BF to ask my questions about the equipment itself—power meters, and tangentially, for me anyway, smart trainers.
But what are THEY comparing themselves to?
Is there some laboratory equipment available?
It seems to me there MUST be, because….
So we have a bunch of viable choices for power meters that seem to all agree, продолжение здесь least to an acceptable level, with some other absolute, theoretical, verifiable calibration standard.
You could just find your zones, as reported by the unit, and work with that.
I also want to have a smart trainer so I can do some indoor training at home to cut out some of my sessions at a local cycling studio.
My plan is to have my coach, who runs the cycling studio, input some of my workouts into Trainer Road and also to experiment with other computer-based apps like Zwift.
But there are many, many complaints from trainer users who also own power meters, that there are often much larger discrepancies between their power meter and their trainer.
This seems even more important if you are using one of these trainers in ERG mode where the app is controlling the resistance of the trainer to match a wattage demanded by нажмите чтобы перейти workout.
It seems that general agreement is that a standalone power meter is more accurate than a trainer, but who knows?
TIA for any answers or references to sources that might help me out.
I might not want to swap the pedals onto my gravelbike, for example; but I want to use the same shoes and cleats.
There is Eco-Powr version of this same cycle that actually places power back onto the grid without any modifications or add ons.
You just plug it into any standard outlet.
You can find it here: My Fuji Norcom Straight 2.
I am going to start a little contraversy here.
I have a power2max and love it.
Now that I have power meter, I am not sure that clipless pedals or clips for that matter, add anything to a time trial ride.
I have been using flats and my adiddas running shoe training.
Can you prescribe an objective test to prove that clipless actually help you time trialing i.
Effectively, throwing away power.
More than most trained cyclists would gain in a year.
Stages is awesome at support and covering people perhaps too often, as some with earlier battery caps have felt.
Hi, first of all i would like to thank you for all your great reviews, i am going to buy power meter but can not be sure which one is, also i can not afford more than 700 Euros are single side stage and pioneer power meters good choices, what are the pros and cons thanks.
Nice post and very informative.
I have the same model P3 as you have in your profile picture, if you will.
Thanks for the fast reply!!
Generally yes, because left-only can be variable from person to person.
Daniel, Depending on your crankset, Power2Max offers MTB compatible spiders.
Stages offers some MTB crank arms Can anyone figure out the difference between all of the current Quarq models?
Will the Riken work?
Potentially new player in the market!
Looks very similar to this one.
Strange thing is I cannot find any credit to your site.
I подробнее на этой странице Speedplay pedals.
Can anyone who has a better understanding of this space point me in the right direction, even if the answer is you need to change your crank setup to get some options.
We actually have a specialized OSBB, which is pretty much a PF30 BB.
I was going for a C1 but found 4 that the crank we have SL-K BB30 is not compatible with it.
A great option and you save about 60 USD versus buying standalone, since you are also changing your gear ratio, Save some weight over the SL-K and get full power, instead of a left only option.
Thanks for the response.
Trying to 4 out whats the most cost effective at this point.
Trying to find a powermeter that measures full power for my current bike, Tarmac Comp with Turn Praxis crankset, and that will also work on a bike I´m planning to buy in a near future Tarmac Sworks.
I was thinking on P2M, any thoughts?
Hi friend, it was a really good article an very compelte, congrats for that.
I have a polar v650 head unit and I agreed with your opinion on look polar system.
Which one do you think ahould I buy?
Sorry, but neither could I get the answer from your introduction to the article.
The issue is in general — what is your opinion on single-leg measuring.
Is it worth the savings?
The double-leg bePRO almost equals in the price to C1.
Or of course dual measurement.
Speaking of which powermeter should I buy, did you see the new Bike Radar youtube video?
Hmm, a lot of missing units — such as 4iiii, C1, Pioneer, and bePro.
All of which are great units.
Ray, Thank you for the write-up.
I love having access to such an in-depth analysis.
That said, I think you should revise your recommendation of the Powertap G3 to include the caveat that is present on читать статью hub meters: installing a hub meter on a Zipp will void the warranty.
I assume similar policies from any wheel manufacturer that no longer sells the rim alone.
I feel like understanding this fact, with the accompanying price drop in crank arm and pedal meters, would have made me make a different choice on which power meter to purchase.
Either way, thanks again.
Dan Clearly this was a time consuming task, so thanks for the write up!
I was thinking in terms of sampling rate vs recorded data so you were correct there.
A new computer capable of storing and downloading all that data is also in the works.
True, but without timelines.
None of them are good at it.
Hi Ray, ROTOR INpower and 2INpower power meters are also able to save data at a rate of 50 Hz when using their User Software in the Advanced Training Mode.
That mode allows to analyze the entire pedal stroke in real time or after the training session.
Hoped you might продолжить чтение some tips.
I have 2 bikes.
A road bike and a a trail bike.
The trail bike I use for just about everything, from XC races to Enduro races.
I have been looking for pedal based PM for months now, and still have not decides.
But I have a problem regarding future pedal based PM.
If I buy this pedal based PM, I also have to buy new road shoes.
And not just one, but three winter, summer, and between.
Although there are different sorts of PM crank, body, … I still prefer to have pedal based PM, so I can easily change between bikes, and they can be both sided measurements.
If so — go PT hub.
If not, then the P2M is a great option.
Assuming any other compatibility issues are moot.
Actually, I´m not planning to move it between bikes, but what I do want, is to buy a Powermeter which will work also on a future bike I´m planning to buy maybe in a year from now which is a Tarmac Sworks.
A crankset would be tied to a bottom bracket standard, though that can certainly be changed if required.
Ray, already decided to go for PT G3, but installation process is DIY and easy??
Thanks Yeah, no joke at all.
Maybe you want to consider the powertap pedals if you are concerned about using it in future bikes, and not having to be stuck with a bottom bracket standard.
Thanks in advance for the advice!
The Stages is certainly a good option.
That was very quick.
I guess it makes sense.
The only issue I could see is probably the limited Защитный наматрасник SkySleep Easy pad Plus 100x210 см from Look and probably not frequent firmware updates if any.
I narrowed down to one option which works best for me, the PTap P1 pedals.
Those are the most versatile option to move from bike to bike, reliable PM and company, good customer support, reads full power, plus I save big in buying top of line pedals for the new bike.
Easy battery change, you can take them with you when you travel and rent or borrow a bike, very versatile.
On top of all that, great costume support.
But correct me if I am wrong, no word about campagnolo owners.
Which power meter would you suggest based on my needs considering a relatively low price as well?
I plan to buy a pedal based power meter and can not decide wheather I should buy Garmin Vector or BePRO.
I am only interested in both sided version, as lately I am strugling with injuries and have probably very asimetric power transfer between legs, which I would like to equalize.
Vector I can get for about 830 EUR can get extra discount from a friendas BePRO for 750 EUR +22 EUR for the rubber band for protecting sensor pod.
So not that big of a difference.
But on the other hand it does have cycling dynamics.
But I do not know how usefull it is.
For me it would probably only come in use smoothness of pedaling to gain more performance is pedaling smoothness included?
On the other hand on BePRO the only thing bodering me is the sensor pod.
I am afraid that I will be constantly damaging it with my pronation feet and shoes.
Rubber band would be needed, but the question is if I would even have room for it.
As I currently use SPD pedal system, I am buying my first road shoes with SPD-SL or Keo Look cleats system.
So I have no idea if there will be room between the sensor pod and my Shoe.
Because I am buying shoes size 47-48.
And I do not know how will also work as I have AddPac (4 FXO, 2×10 BaseT), шлюз very pronation foot.
Does BePRO also have some sort of cycling dynamics?
Sadly BePRO is not at Clever Training in Europe, Otherwise I would probably get it from there, I have tried to contact them, if they will have BePRO, but have received no answer.
Ray, do you perhaps know, if they will have it, and when?
Any recomendation would be very helpful.
Hey folks, need some advice.
I decided to upgrade my trainings and buy a power meter.
After reading articles, forums etc I have 2 finalists for left crank pm also on budget so have to think about price as well So what do you think?
Please advise me … Stages power meter or Pioneer cyclo?
I read that Pioneer would work better or with better data using their head unit.
I have a bunch of Garmins at home so dont want spend more on new headunit until it would bring more functions.
So have you and idea why to choose one instead of other?
Thanks Ray, So with the exact same price is it better to go for Pioneer over Stages just to have a place to possible upgrade in the future?
I want to ask your opinion on: 1.
In other words, are both of the pedals able to communicate with head unit separately?
I mean, your buddies may give you a hard time, but technically no issues.
The clearance between the crank arms and the brakes near the lower wheel would have to be exceptionally close.
In your article on Ant+ FE-C, you recommended to wait Eurobike to purchase a trainer.
Do you have such an advice about power meter?
Any ideal time when to buy?
Thank you very much for an awesome walk through of the Power meter market.
I have bought a Stages Power meter and I have some issues with the calibration.
First I calibrated it and went to a professionally lab where they can apply a certain watt to the bike cyclus 2 and we saw a linear off set of 60 watt in the range from 160 — 300 watt.
After a couple of weeks and a number of calibration, I went back and the linear off set value was now down to 20 watt.
I have just sold my rotor power dual after using it for the past 3 years.
Stages, Precision c pedal PM I.
P1 or Bepro I know for the past 3 years that my power balance has been consistently at 48:52 even after improving my cycling fitness started at 200w ftp and now around 250w ftp Should I just get an affordable 1 sided measurement then?
I want the power reading to be accurate and consistent and if possible no need to zero before each ride.
Do you know somehing about it.
Though may be slower to get to Ireland.
Luckily in Ireland we have a Cycle to Work Scheme which I hope to use to get these which will bring price down further.
Any point waiting for Christmas?
Or will current price be the best yet?
I emailed the Limits logistics team to find out when my PM would be shipped.
I was notified on the 27th 4 September that they had sent it.
Over a week later it has still not been received and no response to further emails asking where the item is.
Whilst I can tolerate delays and teething issues with a brand new product, I cannot tolerate bare faced lies that the item has been sent when it clearly has not.
I will be looking to purchase a 4iii product in the future instead… but I still expect to receive the Limits unit that I have paid for!
If you were me with a 2015 Spesh Tarmac elite bb30 osbb, praxis chain rings, and turn zayante crank arm What power meter, due to the fact that it is hard to find a power meter that is compatible here.
I would need to do something with the bottom bracket, chain rings, crank arm.
Not too excited about buying a wheel set to use a hub based meter.
Hey guys great read, I am using a stages LH crank on the training road bike bike, I have heard there are issues with spike on the MTB when landing back on ground…what is the best PWR option for XC MTB?
They are on sale everywhere.
I just bought Quarz Elsa — full crankset with spider and spindle for the price of Stages left crank only + 40 euro more.
Just browse your local shops.
I have one and I didnt know until I got into the firmware.
A simple example test to show this is try one-leg pedaling.
Since then they introduced their ELSA unit, which also includes the same technology.
RIKEN was also introduced at the same time as a replacement for the older generation Cinqo units.
The only one that measure the real left and right are like the system in TWO pedals Or in two Cranks two sensors eachside.
In that sense both do now have estimated power.
I believe my comparison tables are updated however, though not the text of this older post.
As a side note, be sure to check out my 2016 Power Meter guide here: Hiquestion, can I transfer a quarq powermeter on a sram red 22 gxp crankset 175mm to the same crankset but 172,5.
I heard that the quarq spider was glued to the crank.
Thanks Having suspected посмотреть еще I may have HSV2 back in Sept 2017 after a small rash appeared in my lower region, I had both the IGM and IGG blood tests, both of which registered negative.
A few months into 2018, a similar rash appeared in the same place and get again I had a blood test, which again tested negative for HSV2 antibodies.
My antibodies, doubled and I was clearly positive.
