The Favero Assioma PRO RS Power Meter Pedal is the lightest road power meter pedal on the market, with all the strain gauges, electronics and rechargeable battery sealed inside the spindle for a clean, podless profile. Built around the Shimano SPD-SL cleat system and a carbon fibre reinforced technopolymer body, the PRO RS brings Favero's hard-won reputation for accuracy and reliability into its sleekest, most refined package yet — available in single-sided (RS-1) and dual-sided (RS-2) configurations to suit your training goals and budget.

With ±1% accuracy from Favero's IAV Power System, a standard +53mm Q-factor, a low 10.5mm stack height, and the full suite of advanced cycling metrics including PCO (Platform Center Offset), the PRO RS gives you genuine pro-level data without the pro-level fuss. Install with a 15mm spanner, pair via the Favero Assioma app, and you're training to real power in minutes — and you can swap them between bikes whenever you like.

Choose your variant

• PRO RS-1 (single-sided) — power sensor in the left pedal only, with total power calculated by doubling left-leg output. The ideal entry point for riders who want accurate, reliable power data at the best possible price.
  
• PRO RS-2 (dual-sided) — independent power sensors in both pedals for true left/right balance and the complete Cycling Dynamics suite. The choice for serious training, racing and detailed pedalling analysis.

Already running an RS-1 and want to step up later? The RS-UP upgrade pedal converts your RS-1 into a full RS-2 system without replacing the whole set.
