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.
Power training made simple
It installs in seconds, just like a regular pedal. The Assioma PRO RS also features auto-calibration and instant connectivity via Bluetooth and ANT+, ensuring a smooth, hassle-free ride.
Innovation at the core
What sets it apart? It's the only power meter with electronics, strain gauges, and a rechargeable battery fully protected inside a sleek spindle for unmatched durability and long-term performance. With no electric contacts typical of replaceable batteries, there is no risk of battery-related power dropouts.
No power ports or battery compartments mean no risk of water ingress – backed by an IP67 rating for the whole product’s life, for unwavering reliability even in the harshest conditions.
From MTB to ROAD in minutes
Want to switch from road to MTB and vice versa? With Assioma PRO, you can keep the same spindle and swap the pedal body in just a few simple steps without draining your wallet!
No need for adapters or special tools, and you're good to go.
Every ride precisely measured, every time
Power and cadence are essential, but why stop there? With PCO, Power Phase, Rider Position, TE, PS, L/R balance and more, you gain deeper insights to refine every pedal stroke and push your limits. Unlock your full potential with advanced power data you can trust – accurate, repeatable, and consistent in any weather condition.
No guesswork, just reliable insights to elevate your performance. Pair Assioma PRO RS with your favorite devices for the ultimate training setup.
PCO: The game-changer
Among the few power meters on the market to offer PCO (Platform Centre Offset), Assioma PRO provides a groundbreaking metric that uncovers hidden asymmetries in a cyclist’s pedaling dynamics. By revealing how force is distributed across the pedal, it helps identify inefficiencies, poor cleat positioning, and muscle imbalances.
More than just a wattage reading, PCO highlights help you improve your pedaling technique and cleat positioning and may be helpful in preventing potential injuries.
Precision in every condition
Thanks to IAV Power technology, Assioma PRO RS measures real power even during explosive sprints, high-cadence pedaling, or when using oval chainrings, ensuring unprecedented accuracy on Shimano®-compatible pedals.
Power always within reach
We all appreciate the convenience of rechargeable batteries, but did you know they also eliminate the frustrating power dropouts common with disposables?
With our magnetic charging system, you can power up both pedals simultaneously, ensuring seamless performance with over 60 hours of ride time on a single charge.
On the go? No problem. Top up anywhere with a standard power bank—whether you're at home, or traveling.
