Favero Assioma PRO RS-1 Power Road Pedal

The best power meter pedal to train with precision and ride with confidence! At just 123.5g per pedal, the Favero Assioma PRO RS 1 is the lightest road pedal available. Compatible with Shimano SPD-SL cleats, it offers pro-level performance and up to 160 hours of use per charge — with no drop in performance.

The drive spindle, housing all key electronic components and the battery, is completely sealed and independent of the pedal body. This "split approach" makes it durable and extremely easy to maintain. With a Q-factor of only +53mm and a stack height of 10.5mm, it's engineered for performance on the road. Thanks to its modular design, you can switch between road and MTB setups using the same power sensor.
