Favero ASSIOMA PRO MX-1 (MTB & Gravel power meter pedals with sensor on left pedal)
Favero Assioma PRO MX-1 MTB & Gravel Power Meter Pedals
The Favero Assioma PRO MX-1 is a single-sided power meter pedal system for gravel, MTB, cyclocross and cross-country riding.
It measures power from the left pedal and estimates your total power output, giving you reliable training data without needing to swap cranksets, spiders or bottom brackets. Just install them like a normal pair of pedals, pair them to your bike computer or training app, and you’re away.
These are a good option if you want proper power data for off-road riding, but don’t need the full dual-sided setup of the Assioma PRO MX-2.
Choose the MX-1 if you want reliable single-sided power measurement at a lower price.
Choose the MX-2 if you want dual-sided measurement, left/right balance, and more complete pedalling data.

Why we like them
The Assioma PRO MX-1 pedals keep the clever stuff tucked safely inside the pedal axle, rather than hanging off the outside where mud, knocks and general gravel nonsense can get to it.
They’re SPD-compatible, rechargeable, waterproof rated to IP67, and built for rougher riding — so they make sense for riders who train on gravel, MTB or CX and want consistent power numbers without turning the bike into a science project.
You also get ANT+ and Bluetooth connectivity, so they’ll pair with most popular bike computers, smart watches and training apps including Zwift, Strava, TrainerRoad, Rouvy and more.

Trev’s take
A tidy option if you want proper power data on a gravel or MTB setup without going all-in on dual-sided pedals. Easy to move between bikes, tough enough for off-road use, and far simpler than faffing around with crank-based power meters.
