Favero Assioma UNO Power Meter Pedals

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!


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 DynamicsFavero Assioma 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.


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 is my second Assioma UNO, had other brand on my road bike and changed them to unify with TT bike. The dynamics that these pedals give is so useful if you’re analytic. Both pairs were bought to Power Meter City and I’m very pleased with all the process and customer service.

    • Power Meter City

      Good choice! We hope you will enjoy your new pedals! We are here if there is anything else we can do!

  2. Troy F (verified owner)

    I purchased the favero Uno pedals which seems to be good quality everything mounted like it should, I mounted my pedals on a Nordic track s22i tainer bike paired great with my Garmin fenix 6x pro , but would not pair with my wife’s Garmin forerunner 245 so she can not see wattage data and my Power watt average is always about 50 Watts lower than what my Nordic track s22i says.

    • Power Meter City

      Thanks for the review. I would highly encourage you to trust the power data from your Favero UNO power meter over that of your spin bike. Favero power meters are known for having spot on accuracy and most spin bikes just give a rough approximation.

  3. B-Rad (verified owner)

    These are very un-Italian: They work, seem durable, simple to connect, and aren’t finicky. In short, awesome. And of course PM City rocks too

  10. Olivier Barbès-Morin (verified owner)

    Favero did a great job at making a great pedal. Hardware looks good, feels solid and well built, USB charging cable is long enough so that charging is not a problem in places where there is not an AC outlet every 2 meters. So far the magnetic attachment works very well. On the software side the Android app works very well, pairing was a breeze with my Wahoo Elemnt Roam. Packaging is neat and tidy, instructions for initial setup and battery care are clear and precise. No useless explanations to fill the paper. Regarding Power Meter City, they did a great job at packaging, and sending the package at the proper address Custom paper must have been filled properly since they were no delay or problem at the border. The transport company did a good job at delivering on time (but that’s what they are paid for 🙂 ). So far so good, very happy with the whole customer service experience.

    • Power Meter City

      Thank you Olivier! These pedals are really amazing, we are glad they arrive fast. Good luck on your future rides and we hope you will continue to enjoy your UNO’s. We are here if there is anything else we can do!
