Assioma PRO RS-1
SPD-SL® road potentiometer with power sensor on the left pedal.
Upgrade to PRO RS-2 always available.

Assioma PRO RS is the lightest road bike pedal power meter available, weighing just 123.5g per side.
Compatible with Shimano® SPD-SL® cleats, it offers professional-level performance and over 60 hours of use per charge, without power dropouts.
The axle, which contains and protects all the electronic components and the battery, is completely sealed and independent from the pedal body. This "separate element" approach makes the product durable and extremely easy to maintain. Its elegant design, with a q-factor of just +53 mm and a stack height of 10.5 mm, makes it the perfect ally for improving your performance and achieving results in road training.

The Assioma PRO RS power meter offers ±1% accuracy thanks to the IAV Power system, and provides the most comprehensive power reading available, with a wide range of advanced metrics. The modular design allows you to interchange the pedal bodies between road and MTB while maintaining the same axle.

The best pedal with power meter for training with precision and pedaling with safety.
