Assioma Duo Side Pedal Based Power Meter

These are so well conceived and built. Super-easy to install and remove for travel. You can move them to other bikes if you want. The two-sided version costs more but gives you left/right balance insight. Amazingly compact and lightweight for what they do. Hold a charge for weeks of daily riding and charge up reasonably fast. Email support from Italy is somewhat slow but very helpful and competent.

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.

They are fantastic. I’ve ridden them 10 000 kms over many years. No failure, no maintenance. So I bought another pair for my bike no. 2. They are self-calibrating and when I use them on my Wahoo Kickr Bike they also show exactly the same watt values, indicating they provide close to 100% correct values at all times.

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.

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.
