Experience top-tier road performance with the Assioma PRO RS, the lightest dual-sided power meter pedals on the market at just 123.5 g per pedal. Designed for Shimano® SPD-SL® cleats, these pedals deliver pro-level accuracy, flawless data transmission, and over 60 hours of battery life per charge.
At the heart of the system is Favero’s fully sealed stainless-steel spindle, which houses all electronics and the rechargeable battery. This innovative split-body structure separates the power sensor from the pedal body, ensuring exceptional durability, IP67-rated water resistance, and easy long-term serviceability.
With a +53 mm Q-factor and a minimal 10.5 mm stack height, the PRO RS pedals provide efficient biomechanics for serious training and racing. Powered by Favero’s IAV Power System, they offer ±1% accuracy across all riding conditions—whether sprinting, climbing, or using oval chainrings.
Riders gain full dual-sided metrics such as L/R Balance, Power Phase, Pedal Smoothness, Torque Effectiveness, and Platform Center Offset (PCO). The modular design also allows you to switch between road and MTB pedal bodies while retaining the same high-precision spindle.
Whether you're racing, training, or fine-tuning your riding technique, the Assioma PRO RS gives you the data you need to ride smarter, harder, and faster.
