Designed specifically for MTB and gravel, Assioma PRO MX combines Favero’s renowned precision with a robust construction that stands up to the harshest trails and terrain. At the heart of the system is a fully sealed stainless-steel power spindle, housing all the critical electronic components, strain gauges, and rechargeable battery. This core is completely independent from the pedal body, following a “split architecture” that not only ensures IP67 waterproof protection but also eliminates power dropouts and simplifies maintenance. The 6061-T6 aluminum pedal body, free of any electronics, is built for extreme durability and resistance to impact—without compromising on weight. The SPD®-compatible clipless system is engineered for heavy-duty use, offering a surface hardness up to 800 HV, ideal for the most demanding off-road conditions. Thanks to its modular design, riders can easily swap between MTB and road pedal bodies while keeping the same reliable Assioma PRO power sensor. Powered by the IAV Power System, the Assioma PRO MX delivers ±1% accuracy in all conditions—including sprints, uneven pedal strokes, and even with oval chainrings. Whether you're grinding up steep singletrack or bombing down technical descents, Assioma PRO MX gives you real, reliable power data and access to a full suite of advanced cycling metrics—so you can ride smarter, and harder.
