Favero Assioma PRO RS-1 Power Meter Pedals

Favero Assioma PRO RS-1 Power Meter Pedals Info

The Favero Assioma PRO RS-1 Power Meter Pedals are the lightest road-specific power meter pedals available, weighing just 123.5 grams for the left side power pedal and fully compatible with Shimano SPD-SL cleats. Designed for accurate readings and durable performance, they feature a sealed power spindle that houses all electronics and the rechargeable battery, offering over 60 hours of use per charge without power dropouts. The modular design allows the same power sensor to be used across road and MTB pedal bodies, while the low 10.5 mm stack height and +53 mm Q-factor contribute to a natural and efficient pedaling feel. The pedal body is built from carbon-fiber tech-polymers for added strength and reduced weight.

Using the IAV Power System, the Assioma PRO RS-1 achieves ±1 percent accuracy, even when using oval chainrings. It provides a comprehensive set of advanced metrics including left/right balance, cadence, platform center offset (PCO), power phase, pedal smoothness, and torque effectiveness. A built-in gyroscope and cadence sensor enhance real-time data tracking, all visible via ANT+ or the Favero Assioma app. The Assioma PRO RS-1 is a single sided power pedal made in Italy, offering accurate readings so you can monitor energy and improve on every ride.
