assioma spd power meter pedals Favero Assioma PRO RS-2 Power Meter Pedals

Favero Assioma PRO RS-2 Power Meter Pedals deliver true dual-sided power measurement in a lightweight, road-specific pedal platform designed for Shimano SPD-SL compatibility. By measuring power independently on both the left and right pedals, the RS-2 provides precise, real-time insight into pedaling balance, efficiency, and technique—ideal for riders focused on structured training and long-term performance gains.

At the core of the system is Favero’s sealed power spindle, which houses all electronics and the rechargeable lithium-ion battery in a fully protected unit. This design ensures excellent durability, simplified maintenance, and consistent data accuracy in all conditions. With over 60 hours of battery life per charge, automatic temperature compensation, and an IP67 waterproof rating, the Assioma PRO RS-2 is built to handle everything from daily training rides to race-day demands.

The road pedal body is constructed from carbon-fiber reinforced tech-polymers, keeping weight low while maintaining long-term structural integrity. A slim 10.5 mm stack height and standard +53 mm Q-factor help preserve a natural bike fit and efficient pedaling feel, closely matching the geometry of traditional high-end road pedals.
