Favero Assioma Pro MX – A no-Brainer choice for a MTB Power Meter
More: Vendor and retailer sites
These are the go-to pedals for MTB, CX, Trail and Gravel. Optionally available in a dual-sided power variant.
Favero is a lesser-known brand than Garmin. Yet its pedal-based power meters have been around for as long and have been renowned for their accuracy and reliability from Day 1. Oh, and did I say they are notably cheaper than Garmin?
Even in the rare, worst case where your pedal body breaks a replacement is a mere Eu49.

Reasons to avoid the Assioma MX
Other than the 60-hour battery life, which is still great, I can’t see any reason.
Accuracy
dcrainmaker and gplama channels both cite near-perfect accuracy.

will they release a new road version? i’m in the market for a power meter, the actual assioma duo was released back in 2019
I would expect that to happen.
The MX is going to be ramping up production this year, apparently it will be in short supply initially. so we have to ask if there would be production capacity for a new Road version this year. I guess not.
i think a new road version in a year’s time, the obvious changes being the in-spindle design, PCO and battery life changes. Other than aesthetics it wont be worth the upgrade. as you probably know Assioma seems to last forver!
