Built for the demands of mountain biking and gravel riding, the Assioma PRO MX is an off-road power meter that blends Favero’s industry-leading accuracy with unmatched durability. Designed to endure rugged terrain and tough conditions, it features a dual-sensing pedal system with a fully sealed stainless-steel spindle housing the critical sensors, electronics, and long-life rechargeable battery. The electronics are entirely separated from the pedal body in a smart “split-architecture” format, boosting maintenance ease, preventing data loss, and providing full IP67 waterproof protection. The replaceable pedal body—crafted from premium 6061-T6 aluminum—is impact-resistant and lightweight, ideal for technical trail performance and endurance cycling. The SPD-compatible clipless MTB pedals are optimized for aggressive use, offering a surface hardness of up to 800 HV, giving you secure engagement and long-term wear resistance. With a modular design, the Assioma PRO MX lets you switch between MTB and road pedal bodies without changing your core power tracking pedals—a great option for multi-discipline cycling enthusiasts. Powered by Favero’s IAV Power System, it ensures consistent ±1% accuracy whether you're sprinting, climbing, or using oval chainrings. From steep climbs to rocky descents, the Assioma PRO MX equips riders with precise, real-time bike power data tools and in-depth cycling metrics—so you can push your performance further with complete confidence.
