The Favero Assioma UNO Power Meter Pedals are the single-sided version of the Assioma DUO power meter with a power sensor located in the left pedal. The Assioma UNO works by doubling your left leg power in order to derive your total power. It is every bit as reliable and consistent as the DUO and because it contains just the left pedal sensor, it is priced at only $459, making it the most affordable power meter pedal you can buy!
In addition, the UNO Power Meter Pedals have all of the features found in the DUO. You get ANT+ and Bluetooth SMART, a rechargeable battery with 50-hour life and of course Assioma’s +/- 1.0% accuracy levels. Yes, that’s right. Using Favero’s IAV Power Technology, the Assioma UNO is accurate to +/- 1.0%.
The new Assioma is also easy to install. In fact, it installs just like a normal pedal. Just grab an Allen key and screw it on. Easy as that!
Favero Assioma UNO Highlights
Accurate with IAV Power
The Assioma uses Favero’s IAV Power Technology. IAV results in accuracy of +/- 1.0% and allows the Assioma pedals to be used with oval chainrings without any impact to the accuracy of your data!
Easy to Install & Transfer
Installing a power meter doesn’t get any easier. Grab the Allen key, screw on the pedals and you’re ready to go. This means you can also move them from bike to bike in seconds!
ANT+ & Bluetooth SMART
With both ANT+ and Bluetooth SMART, you can use the pedals with your favorite cycling computer, GPS watch, smart phone or tablet. The choice is yours!
Rechargeable
The Favero Assioma uses a rechargeable lithium-ion battery with 50-hour battery life. When the battery gets low, simply plug them in using the included charger, and you’re good to go again.
IAV Cycling Dynamics
Favero’s integrated gyroscope also allows you to measure cycling dynamics data such as IAV Power Phase and IAV Rider Position. With these advanced metrics, you can become a faster, stronger rider!
Proved and Guaranteed
Each Assioma undergoes strict control tests (load, shock, fatigue, wear, water resistance, etc.) in order to ensure maximum performance and comes with a full two-year warranty.
Favero IAV Power Technology
The Favero Assioma UNO uses Favero’s IAV (Instantaneous Angular Velocity) Power. Using special software and a built-in three-axis gyroscope, IAV takes into account the precise pedaling speed within each pedal stroke. This results in the Favero Assioma UNO having accuracy of +/- 1.0%. In addition, IAV allows you to use the Assioma pedals with oval chainrings without any impact to the accuracy of your data!
Favero IAV Cycling Dynamics
Favero’s gyroscope also allows you to measure cycling dynamics data. IAV Power Phase displays the portion of your pedaling stroke in which torque is produced. In addition, your Power Phase Peak, in which maximum torque is produced, is also indicated. IAV Rider Position displays the portion of time you are in a seated vs. standing position. Therefore, you can see how a specific position can influence your performance. IAV Cycling Dynamics works with the Garmin Edge 1030, 830, 820, 530 and 520 Plus.
Updated Spring Tension
Favero recently changed the spring in order to have a wider release torque tension and these pedals come with the new spring. The new spring’s release torque tension has been lowered from 11Nm to 8Nm. Therefore, the pedals are now easier to clip in and out of.
Now with Auto-Zero
With the release of firmware version 4.75, the Assioma pedals now have auto-zero built in. With this feature, the pedals will calibrate on their own – no need to manually do it on your bike computer before your ride. This saves you time and ensures your power data is always accurate!
Favero Assioma UNO Pedal Cleats
The Favero Assioma UNO comes supplied with red, 6-degree float cleats. You also have the option to purchase black, 0-degree (fixed) float cleats. If you have LOOK KEO cleats, they will also be compatible with the pedals.
Compatibility
Bike: The Favero Assioma power meter pedal is compatible with any road or indoor bike.
Cleats: The power meter uses a LOOK Keo style 3-bolt road cleat. One set (red 6-degree float) comes supplied with the power meter. You may also use LOOK Keo original cleats with the power meter. In addition, the LOOK Keo Grip cleat (sold by us separately), features a non-slip surface, which makes walking easier and safer.

This product has been great. Very easy to install and set up. While riding you would not know that only one pedal is registering power. PMC shipped my order immediately and it was in my hand in Idaho in just a few days.

I got the Uno about a month ago and am very satisfied. I can switch it between bikes quickly and have it paired easily with my laptop for zwift as well as my Wahoo Bolt. Honestly haven’t had a single pairing issue which isn’t always the case with a lot of sensors. It also doubles as a cadence sensor which is nice. It shipped super quickly. All the way to the east coast in 3-4 days despite COVID issues slowing down shipping lately (I got a notification that my order was shipped just a few hours after my I placed the order). Very satisfied with powermetercity. I saw them recommended in some of the power meter reviews I was looking at and I’ve been satisfied with the service I received. The one potential error is that there seemed to be a missing washer in the cleats bag. It could have been that I dropped it but that didn’t seem to make sense as I was very careful and searched thoroughly. Anyways, the cleats have been secured well even with a missing washer which I’ll probably replace at some point. I definitely recommend the Assioma Uno as well as Power Meter City. I already recommended both to a friend but unfortunately the Uno was sold out at the time.

As soon as PMC let me know the Uno was back in stock I placed my order. A couple of days later they were on my doorstep. I installed them the next day and was up and running, I mean cycling, in just a few minutes. Initial calibration took seconds and they showed up on my Wahoo Elemnt as soon as I turned it on. I chose these pedals at a higher cost than crank arm because I can transfer them to another bike in just a few minutes. Looking forward, I don’t have to worry when I get my next bike. My rides have been been getting faster and I feel more motivated. This has been a big help since most of my riding partners have dropped out of the group ride scene since the pan(dem)ic started. It’s harder to push myself when riding alone. Favero is my new riding partner. Thanks PowerMeterCity!

The Favero Assioma Uno pedals are incredible. I have tested them against my Wahoo Kickr and the accuracy is dead on. These are very easy to set up, use and charge. The price is worth it for the ease in access to professional level data.

First, tip of the helmet to Power Meter City. The world was back ordered on the Favero UNO’s. PMC was back ordered as well but indicated they’d ship in two weeks. With everything going on, I expected much later. As promised, two weeks. Amazing service. I have the Vector 3’s and they’re great until you need to change the battery. I’ll take the hit on user error. Being able to charge the power meter…game changer. Charged, installed, paired, went for a ride. Awesome.

I was surprised at how small these pedals are in size. Make no mistake, these pedals offered the smoothest ride. The 6 degree float cleats provided an amazing cycling experience. They were easy to clip in and out of and my knees haven’t felt this good after a ride in a very long time. This pedals are definitely worth the investment. I can’t wait to ride again.
