What Our Gearhead(R) Experts Are Saying: "I've tested a lot of power pedals, but the Assioma PRO RS-1 stands out. It's light, precise, and I never worry about data dropouts-even on long rides. Being fully Shimano cleat compatible is the cherry on top." We train to the watt and race with precision using the Favero Assioma PRO RS-1 Pedal. This ultra-lightweight power pedal delivers elite-level performance with full Shimano SPD-SL(R) cleat compatibility and one of the lowest stack heights in its class. Whether we're chasing PRs on steep climbs or fine-tuning intervals, the PRO RS-1 gives us reliable, high-fidelity data to fuel every effort. The left-side power sensor uses IAV technology for 1% accuracy, even with oval chainrings, and captures advanced cycling metrics like PCO, power phase, and pedal smoothness. A modular spindle design separates the electronics from the pedal body for easier maintenance and long-term durability. With over 60 hours of rechargeable battery life, robust waterproofing, and sleek road geometry, this pedal keeps us locked in on performance with every turn of the crank.
