assioma right pedal Favero Pedals Assioma PRO RS-1

Favero Assioma PRO RS-1 Power Meter Pedals deliver single-sided power measurement in a true road pedal built around Shimano SPD-SL compatibility. The system places the power sensor on the left pedal and calculates total power by doubling left-leg output—an efficient way to bring structured training to any road bike without swapping cranksets or chasing compatibility.

Favero’s sealed power spindle houses the electronics and rechargeable lithium-ion battery, keeping the sensitive components protected and making day-to-day use simple. With an IP67 waterproof rating, temperature compensation, and over 60 hours of runtime per charge, the Assioma PRO RS-1 is designed for consistent data through long training blocks, rough weather, and travel.

The road-specific body is made from carbon-fibre tech-polymers to balance durability and low weight. A low 10.5 mm stack height and standard +53 mm Q-factor help preserve a natural fit and stable pedaling feel, while the clip-in interface remains fully compatible with Shimano SPD-SL cleats (including the included cleats, plus Shimano SM-SH10/11/12).
