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.

I purchased the UNO pedals to use primarily with Zwift. The installation/set up was really easy and the power meter paired immediately with both the Wahoo and Zwift apps. It has proven to be both accurate and reliable. The battery life is really a plus- only charged once in over a month of use!
Highly recommend purchasing from Power Meter City. Price is very competitive and shipping was right on time. Also, knowing that they stand behind their products and are U.S. based is very important to me.

What a great piece of kit. Super easy to set up and so far really reliable. Pairs and works just like you’d expect any other power meter to. Can’t wait to travel with them and have power on the go as well! Pedal-based power will open up a lot of options that don’t require me to bring one of my bikes with me everywhere.
