Favero Assioma Duo Shi

Four years after the original Assioma power meter pedals, Favero has modified the cartridge design to fit Shimano SPD-SL pedal bodies.

Just like the Garmin Rally, you can now have power meter pedals that are compatible with Shimano SPD-DL cleats.

Shi is a shortening of Shimano.

Assioma Duo Shi – In a Nutshell

This version of Assioma is essentially identical to the previous models from a performance perspective and is only available in the dual-sided format. No pedal body is included and you have to disassemble your current Shimano pedals to transfer across the pedal body…an easy DIY task.

Favero says that there is a different factory calibration process and an oil retainer is glued on the axle but I guess we don’t really need to know that but it is worth knowing that there is compatibility only with these Shimano pedal bodies: PD-R8000, PD-R7000, PD-6800, PD-R550, and PD-R540.

Favero Assioma Duo Shi Specifications Overview

Take Out

I used the original bePro and Assioma Duo a lot over the last 6 years and they are extremely reliable and accurate. Recently I stopped using Assioma just because I was getting fed up with the Look/KEO cleats. I switched to a Shimano R9100P and P2M despite knowing the issues of the former. Now I have the option of swapping across my Shimano Dura-Ace or Ultegra pedal bodies I will probably move back to Assioma.

In the round, Assiomas are probably better than Garmin Vector 3 and Rally, especially if you take COST as a factor. You can see the specs, above, but they are not worth fretting over as they are perfectly fine and will keep almost all of you happy. Pretty much the only common reasons to NOT buy Assioma would be Aesthetics and a lack of dual-BLE broadcast (debatable). Others amongst you might bemoan the weight, Q-Factor and lack of PCO metric if you have highly specific needs.

We have reached Peak Assioma.

This is the last major upgrade that Favero can make to the Assioma product set. Even if there is another generation planned (no intel) and even if that improved accuracy it would be irrelevant in practical terms as +/-1% accuracy is all 99% of us need. Sure Favero could make Assioma a bit smaller and a bit prettier and get the battery to last a bit longer but none of those improvements would be a game-changer. It’s time for Mr Favero to cash in and sell!

  1. Do they get to avoid paying the Shimano licence fees by shipping without the body? Fairly novel solution if so.

    I have been waiting for the right power meter – was turned off by the Look cleat options, and the eye-watering price of the new Garmins. Going to order these now!

  2. hi, thank you for the info. I already have the favero power meter, Do you know if there’s any restriction just to swap the pedals to Shimano or do I need a special kit? Easy to do it? I’m not a mechanic by any means… Do
