Overview

The Product
Assioma PRO MX is the revolutionary pedal-based power meter for MTB and gravel, 100% SPD® compatible. It can be used both with the included cleats and with original Shimano® SM-SH51 cleats. It inherits the reliability and extreme precision of Favero's road pedal power meters, integrating unmatched shock resistance and trail-ready toughness.

Easy to install and universally compatible
The Favero Assioma PRO MX-2 pedal power meters install and move from one bike to another like any other pedal: in just minutes, without special tools or a mechanic's assistance. Thanks to the integration of both Bluetooth and ANT+, they are also compatible with most cycle computers and smart watches on the market, as well as with major training apps such as Zwift, Strava, Bkool, TrainerRoad, Rouvy, and many others.

A compact axle to protect the technology
All electronic components and the integrated rechargeable battery are completely enclosed within an extremely compact and resistant axle. Thanks to the strategic placement of the rechargeable battery and the absence of external electrical contacts, unpleasant battery-related dropouts, typical of replaceable batteries, are avoided. Furthermore, with no battery compartments or openings that can be opened and closed, water, mud, and dust cannot enter, thus ensuring extreme reliability even in adverse weather conditions. The product is IP67 certified.

Ultra-resistant against shocks and impacts
The 6061-T6 aluminum pedal body is extremely robust and ultralight, ready to tackle the most demanding terrain. The engagement system has a surface hardness of up to 800 HV, for impact resistance never before seen in a pedal power meter.

The IAV Power System and data measured by Assioma PRO MX-1
Thanks to the special IAV Power System, Assioma's measurements account for our irregular pedaling (e.g., sprints, climbs) or the use of oval chainrings when calculating power, thus guaranteeing an accuracy of ±1% in any situation. Assioma PRO MX-1 offers extremely comprehensive data reading via ANT+ and Bluetooth.

The visible data are:
Power
Cadence
PCO (Platform Center Offset)
PP (Power Phase)
TE (Torque Effectiveness)
PS (Pedal Smoothness)
RP (Rider Position)

Real L/R Balance data, not estimated
The data provided by Assioma PRO MX-2 is based on measurements taken separately on the right and left sides.
This allows for accurate observation not only of total power but also of the L/R balance, resulting in real, not estimated, data reading.

Rechargeable and eco-friendly
Assioma PRO MX uses integrated rechargeable batteries: a single charge guarantees at least 60 hours of use. Charging is done via a magnetic system that avoids any issues related to accidental tugs on the charging cable.

Made in Italy
Favero Electronics produces each power meter at its headquarters in Italy and individually tests its proper functioning through careful laboratory tests, amply satisfying the standards required by current regulations.
