Favero Power Meters

Favero Logo

Favero makes one of our most popular power meters we sell – the Assioma power meter pedal. They make two versions: the DUO and the UNO. With both versions, you get both a left and right pedal. However, the DUO has a power sensor in each pedal and therefore measures left and right leg power. The UNO has a sensor in only the left pedal and measures left leg power. The Favero power meters are the most affordable power meter pedal and are accurate to within 1.0%. In addition, they feature a rechargeable battery, Bluetooth SMART and have a wonderful track record of reliability.

Additional Information:


Both the Assioma DUO and UNO are a breeze to install. Simply grab an 8 mm hex wrench and screw them on – just like a normal pedal. This also allows them to be moved between bikes quickly and easily. Once installed, Favero power meters do have some one-time set-up steps such as registering them with the app taking a quick ride to set the installation angles. Its easy stuff and is outlined in the manual so be sure to give it a quick read.


The Assioma is the lightest power meter pedal available, weighing in at 149.5 grams per pedal. This is only slightly heavier than a standard road pedal.

Power Measurement

The Assioma DUO measures both legs and also measures left/right leg power. This means it can tell you how much power each leg is generating. The Assioma UNO measures left leg power and like all left-side power meters, doubles the left leg value to give you total power.

Special Features

The Favero power meters are the only ones with IAV (Instantaneous Angular Velocity) Power. This special software and integrated three-axis gyroscope results in accuracy of +/- 1.0%. In addition, IAV allows you to use the pedals with oval chainrings without any impact to the accuracy of your data.


Favero power meters use rechargeable lithium-ion batteries. Battery life is around the 50-hour mark, which is good for a rechargeable battery.

Communication Protocol

Favero power meters transmit data via both the ANT+ and Bluetooth SMART wireless protocols. Therefore, they are compatible with just about any bicycle computer. You can also use a smart phone or tablet as your head unit.


Featuring IAV Power Technology, Favero power meters are accurate to within +/- 1.0%. This is on par (to slightly better) than the majority of other power meters on the market.

Cadence Detection

Like most power meters, the Assioma DUO and UNO use an accelerometer to measure cadence. This means you don’t have to worry about attaching a magnet to your frame.


Favero power meters come with a two-year manufacturer’s warranty.
