Favero Electronics Assioma PRO RS-1

The Assioma PRO RS, weighing only 123.5 g per pedal, is the lightest road bike power meter pedal on the market.
Compatible with Shimano® SPD-SL® cleats, it offers professional performance and over 60 hours of runtime per charge – without power interruptions.
The axle, securely housing all essential electronic parts and the battery, is fully 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 only +53 mm and a stack height of 10.5 mm, makes it perfect for improving performance and achieving results in road training.

The Assioma PRO RS power meter offers ±1% accuracy thanks to the IAV Power System and the most comprehensive available power data display with a variety of advanced metrics. Its modular design allows you to switch between road and MTB pedal bodies while using the same power sensor.

The best power meter pedal for precise training and secure riding.
