The Favero Assioma PRO RS-1 sets a new benchmark for precision, weight, and performance in single-sided power-meter pedals. At just 124.8 grams per pedal, it is the lightest road power meter available—engineered for riders who demand maximum efficiency without compromise. Fully compatible with Shimano® SPD-SL® cleats, the PRO RS-1 integrates seamlessly into existing setups while maintaining Favero’s hallmark accuracy and reliability. Its carbon-fiber-reinforced polymer pedal body and sleek 10.5 mm stack height deliver a natural, responsive pedaling feel, while the optimized +53 mm Q-factor ensures perfect alignment and comfort across all riding intensities. Every watt is measured through Favero’s proprietary IAV Power System, guaranteeing ±1 % accuracy even when using oval chainrings or varying cadences.

At the heart of the PRO RS-1 is Favero’s innovative “split-architecture” spindle design, which houses all electronics, sensors, and the rechargeable lithium-ion battery inside a completely sealed stainless-steel spindle. This separation from the pedal body not only enhances waterproofness to an IP67 rating but also makes maintenance straightforward and cost-efficient. A single charge provides over 60 hours of ride time, and magnetic USB charging ensures quick, reliable top-ups without wear on connectors. The modular spindle design also allows riders to swap pedal bodies between road and MTB configurations, offering unmatched versatility for multi-discipline cyclists. Engineered and assembled entirely in Italy, every detail of the PRO RS-1 speaks to Favero’s commitment to precision craftsmanship and durability under real-world conditions.

Beyond raw power measurement, the Assioma PRO RS-1 provides advanced cycling dynamics to elevate every training session. Riders can access metrics such as Platform Center Offset (PCO), Power Phase (PP), Pedal Smoothness (PS), and Torque Effectiveness (TE), delivering insights into balance, efficiency, and pedaling symmetry. Data transmission via ANT+ and Bluetooth ensures compatibility with all major head units, training platforms, and mobile apps, making integration effortless. Whether you’re analyzing race efforts, refining pedal stroke efficiency, or chasing marginal gains, the Assioma PRO RS-1 turns every ride into actionable performance data. Lightweight, durable, and exceptionally precise—the PRO RS-1 is the ultimate tool for road athletes who demand pro-level feedback in a minimalist, race-ready form.
