OVERVIEW
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.
The best power meter pedal to train with precision and ride with confidence.
