Favero Assioma RS-1 Power Meter Pedals - Shimano - Single Sided

Assioma PRO RS is the lightest road power meter pedal available, with just 123.5g per pedal.
Compatible with Shimano® SPD-SL® cleats, it delivers pro-level performance and over 60 hours of use per charge-no power dropouts.
The power spindle, which safely houses all the important electronic parts and battery, is completely sealed and independent from the pedal body. This so-called "split approach" makes it durable, and extremely easy to maintain.
Its sleek design, with a Q-factor of just +53mm and a stack height of 10.5mm, makes it perfect to improve performance and achieve results on your road training.



The Assioma PRO RS power meter offers ±1% accuracy thanks to the IAV Power System, and the most complete power data reading available with a wealth of advanced metrics. A modular design lets you switch between road and MTB bodies while keeping the same power sensor.
