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.

dcrainmaker and gplama channels both cite near-perfect accuracy.

My favourite kit and nutrition
- Maurten — the race nutrition trusted by elite athletes. Gels and drink mix engineered to be easy on the stomach.
- Garmin 90-degree charging adapter — the small adapter that keeps your charging cable tidy at the stem. Essential for race day.
- Garmin charging puck — the fastest and most reliable way to top up your Garmin before a session.
- Ravemen FR300 — front light that mounts directly under your Garmin or Wahoo head unit. Keeps your bars clean and your beam pointed where it matters.
- Garmin Varia RTL515 — radar rear light that alerts you to vehicles approaching from behind. Pairs with your Edge or Garmin watch.
- Stryd — the footpod that brings running power to your Garmin. The single most useful running upgrade I have made.
- Favero Assioma Pro RS2 — the power meter pedals most serious cyclists end up choosing. Accurate, easy to move between bikes.

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!
