The Favero Assioma PRO RS-2 Power Meter Pedals deliver cutting-edge dual-sided power measurement for riders who demand precision, reliability, and seamless integration with Shimano SPD-SL systems. Engineered and manufactured in Italy, these pedals combine advanced metrics with effortless installation and connectivity, empowering cyclists to maximize their potential on every ride. What sets the Assioma PRO RS-2 apart is its innovative internal design, electronics, strain gauges, and a rechargeable battery are fully protected inside a sleek spindle for unmatched durability and long-term performance. With no external battery compartments or power ports, there&';s zero risk of water ingress or battery-related power dropouts. An IP67 rating ensures unwavering reliability even in the harshest conditions, ride after ride. Installing in seconds like regular pedals, the Assioma PRO RS-2 features auto-calibration and instant connectivity via Bluetooth and ANT+, pairing seamlessly with bike computers, smartwatches, and popular training platforms like Zwift, TrainerRoad, and Rouvy. The system&';s portability allows riders to easily swap pedals between bikes, maintaining consistent power data across their entire fleet. Built for performance optimization, these pedals feature 100% SPD-SL compatibility with precise clip-in/clip-out, adjustable release tension, and a 10.5mm stack height for optimal power transfer. The standard +53mm Q-factor delivers tighter, more precise cornering characteristics that competitive riders demand. Beyond basic power and cadence, the Assioma PRO RS-2 unlocks advanced metrics including PCO (Platform Centre Offset), Power Phase, Rider Position, Torque Effectiveness, Pedal Smoothness, and L/R balance. The groundbreaking PCO metric reveals hidden asymmetries in pedaling dynamics, helping identify inefficiencies, poor cleat positioning, and muscle imbalances-insights that improve technique and may help prevent injuries. Powered by IAV Power technology with a three-axis gyroscope, the system captures every pedaling variation for 1% precision in all conditions, explosive sprints, high-cadence efforts, or oval chainrings. With up to 160 hours of battery life per charge and a convenient magnetic charging system that powers both pedals simultaneously, the Assioma PRO RS-2 keeps riders focused on performance, not maintenance.
