Assioma Duo Power Meter Pedal

I use these pedals on my outdoor road bike, as well as a road bike on an indoor trainer. I've easily put 3000 miles on them, and have had literally no issues with it dropping out during a ride, or any other sort of glitch with respect to tracking power (and cadence!), whether paired to my Garmin Edge 520 Plus (when outside) or Zwift (when inside). Usability/Accuracy: Inclusion of both ANT+ and Bluetooth is welcome, to support pairing with both phones and indoor trainers...the former being useful if you don't have a dedicated cycling computer but want to pair the pedals to something like the Strava iPhone app to track your rides and power data. I use them indoors and out since they are very easy to install/remove, as they even supply a beefy Allen wrench with the pedals (try doing that with a crank-based system). Not that I have compared them to other power meters to determine accuracy (or am even able) , but DC Rainmaker on YouTube has reviewed these pedals and has at his disposal many power meters and awesome software to compare recorded data, and found these to be extremely accurate compared to far more costly devices (including Garmin Vector 3). On my long rides, I've noticed no weird swings in power measurement, as power readings seem stable and consistent. Battery: I've think I've charged these no more than 3 times since buying them, and yet I certainly did not let the battery go down to anywhere less than 10%...after 3000 miles of riding! The magnetic chargers are really slick and make charging real easy...I just use a portable battery pack to charge it and let it charge in my garage while hanging on the wall. Features: Not many months ago, Garmin opened up cycling dynamics to the Assioma platform, which goes way beyond measuring just power, but can give you L/R balance, power phase, riding position and so on...more data to geek out on! See the pics attached to this review to see the metrics you get when viewing data in Garmin Connect should you have a Garmin Edge cycling computer (only "Platform [Center] Offset" within Garmin Cycling Dynamics is not supported).

First, bear in mind the following: I have never trained with a power meter before so I have no prior experience with power, or a basis for comparison. Also, I've only had these pedals for barely 3 weeks at this point. I've logged 8 rides on the pedals since I've bought them. My review will be based on the short time I've spent with these pedals thus far. The Assioma Favero pedals are AWESOME. Really, they are. I did my homework before buying these. I spent about 4 months slowly accumulating and reading numerous articles and YouTube videos/reviews on various power meter systems. There are two platforms: crank-based and pedal-based. I only ever wanted pedal-based power for 2 reasons: first, I need to be able to swap the power meter between bikes - I keep my old road bike in Japan and ride it when I'm there - and second, crank-based power meters are far more expensive. Crank-based systems seem to be perhaps 1% more accurate than pedal-based systems. I don't care about a 1% difference; it's pedal-based for me. So within pedal-based systems, there are your mainstream options like Garmin and Powertap. Had I not spent so much time watching out for power meters, I probably would have gone for one of those options, and I'd probably have been fine with them. However, I read several reviews about the Garmin pedals being glitchy (just like their head units...). One day I saw a very positive review of the Assioma Favero pedals by a YouTuber who I highly trust. After that review I had it in mind to go with Assioma but held off for a few months making sure all the other reviews I came across were also positive, which they were. Having received the pedals, they are everything I had hoped for. As advertised, they install easily, the set up via iPhone was very straightforward, they charge very easily and are extremely low maintenance. I calibrate them before every ride - it takes less than 30 seconds - and they just work beautifully. I believe they hold charge for 50 hours, and I haven't had to recharge them since the initial charge. My only wish is that the pedals showed more watts - but that's the fault of my legs not the pedals. Seriously though, these pedals are fantastic and sell at a very competitive price point. Despite not having spent enough time using the pedals for a long term review, I can give my unqualified recommendation based on my short experience so far.

I bought them a year ago and I had no problems with them. Installing them is extremely simple, in addition to bringing the Allen key to do so. They are extremely consistent and work equally well in humid, warm or rainy weather. The battery really lasts + 50 hours as indicated by Favero. If you use power analysis software such as WKO5 it is possible to see metrics such as pedal smoothness, torque effectiveness, L / R balance (in the case of Assioma Duo, the ones I bought). I recommend using them with the Look cleats, they work perfectly, some people consider that the pedals have a lot of tension but in my case they have worked correctly, they are easy to attach and decouple. Pods can be a concern (even aesthetic) for some people. They practically do not notice once the shoe is attached to the pedal and does not protrude from the crank (I used Ultegra 6800 and R8000). They don't touch anything and are extremely light. They don't add to the Q-factor so they won't spoil your bike fit. Before these pedals I used the Shimano Ultegra. Do not be afraid to change from one system to another, they are basically the same, if you are able to use the shimano cleats, you simply will not notice a difference in the operation (this out of personal tastes, the mechanics are the same). The application works in a simple and effective way, either to see the battery status, define the crank length or to update the firmware. I think that for those looking for a reliable, accurate, accessible and pedal-based powermeter to transfer it to several bicycles, you cannot fail with these.

These pedals are super easy to install and switching the pedals between bikes is as easy as swapping out normal pedals. They are also very light for power-meter pedals -- about the same weight as my 105 Shimano pedals. The battery charge lasts forever. I ride about 1-2 hours every day during the summer and have to charge them only about once a month. Charging is easy, too; no need to take them off your bike. Also, they're not bulky like some power-meter pedals. There is no wonky dongle or bulky batter pack that might scrape the road during tight cornering in a crit. They look like normal pedals. Only your most intimate friends will even know your secret. Having power readings from both pedals is a nice feature, of course. I think this has helped me improve my pedal stroke. When I first started using the pedals, I'd typically average about 47/53 left-right balance. This prompted me to start stretching the crap out of my left leg and pretty soon I was often averaging a 50/50 balance. I have a Wahoo Bolt computer and there's never been a signal drop between the pedals and computer. But one minor complaint: my Wahoo consistently underreports my kilo-joules expenditure (and hence my calorie expenditure, too) by about 20%. I suspect that this is Wahoo's fault, not the pedals. Wahoo needs a firmware update to fix the problem. I know that the wattage from the pedals is accurate, though, because I can switch between my PowerTap hub power-meter and the pedals, the power reading is nearly identical. Bottom line: these pedals are a great bargain. Best power-meter for the money in my view.

Update: I just wanted to hop on to update my review to continued excellence. I have used these for more than a year with absolutely no issues at all. Battery lifespan continues to be outstanding. I periodically put my chargers on just to top off and to keep the nodes working. Connections with my wahoo set up inside and with my head unit remain solid with no issues. I have dropped some weight and the power is accurate (compared with another readout on a totally different set up with different meter). I can’t speak for anything manufactured beyond when I purchased mine, but these continue to be a solid, top product. I don’t know why anyone would purchase anything else. If the company is reading these reviews, I would kill to be an athlete for you all! Your meter is that good (I wish I was comparably as fast!) Excellent product. Power is accurate. Pedals are solid, with a slightly wider profile than the Look Keo carbon blade. I had my shop install them so I can’t speak to install, but it took no time for the mechanic. These had come highly recommended by a cycling coach from a well known training company. I was surprised, figuring they had access to the high-end meters, but after a couple of months of use, they are doing what they should. Battery life is excellent. The one potential irritant is do not put the pedals in travel mode unless you have to for a flight. I misunderstood what they meant by travel. Had to drive 6 hours to an event so put them in travel mode to save the battery. I didn’t bring the charger. You can’t get them out of travel mode without the charger. Seems this is a fairly common amateur foul because I found a number of posts asking if there was a work-around. Save yourself the frustration and embarrassment: don’t use the function unless flying. And bring your charger! Other than that, these are a huge bang-for-your-buck addition if you don’t have the money. No issues. Really pleased. And it’s improved my training.

Bought these for use on the road and on a smart trainer. The bike didn't have a power meter previously and my smart trainer's power meter was unreliable. Installation was simple. The pedals connected with no issues via ANT+ both to my Coospo BC200 bike computer and to Rouvy running on a Windows 11 tablet with an ANT+ USB dongle. Main reason for buying the Duo model, rather than the Uno, was to be able to see left/right power balance. The BC200 can display that. I haven't found a left/right balance display option in Rouvy. I used the Favero Android app to configure and register the pedals, and update their firmware. No issues there, but I did notice that the phone needs to be within a few feet of the pedals for the firmware update, closer than what's needed for the bike computer or Rouvy dongle to receive the pedals' signal. Using these with Look Keo gray cleats. The float on the Faveros is slightly more than with the same cleats on Look Keo 2 Max pedals. The Favero release tension spring is strong. If you're having problems clipping in/out -- I did with the default tension setting, even after 10+ years of using Look pedals -- adjust the tension setting bolt at the rear of the pedal.

I said “goodbye/good riddance” to Garmin Vector 3 (dual) and “hello/hallelujah” to Favero Assioma DUO. It was a wonderful to change and use a pedal-based power meter that WORKS perfectly! Install is simple-and-easy. Charging design is perfect, with outstanding battery life. Super sturdy, durable and solid design and construction. Power data is spot-on and an amazing asset to use in training and racing. I use these pedals with TrainerRoad + CycleOps Hammer and have an outstanding indoor training experience. Pairs and works perfectly with my head unit. Not getting data? Just hit the calibrate button on your app or head unit and you'll start seeing your power numbers. I can’t recommend these pedals enough, a smart and affordable choice! Check-out the DC Rainmaker review and comments to understand how great these pedals are. Avoid Garmin Vector pedals, not worth the money/time/hassle.

My second pair. Assiomas seem to be accurate and easy to install and manage. I bought the first pair from Google express and they would not exchange or take returns. Right pedal was discharging at twice the rate as left pedal. I didnt want to send them to Italy leaving me without powermeters so i bought a second pair to use on another bike. May or may not send the other pair in. I just throw the charger on them once a week. The price on these were almost $200 more then what I paid last year, but they are hard to come by so I bit the bullet and paid the extra.
