I’ve been using Assioma Duos for almost 6 months now and so far they’ve been bullet-proof.
It was between these and the Vector 3s, with my head telling me to go Garmin, but my heart saying listen to the reviews and go with Assioma. To be honest, the main hang up I had was with the appearance of the Assiomas, with the pod on the axle. However, once you’re clipped in and spinning, you quickly forget its there.
Accuracy-wise, they are spot on with my Kickr and a huge improvement on my L Only Stages.
The pedals that shipped to me had the updated springs in the clip (black as opposed to silver) and I’ve had no issues with tension.
The only slight issue I had was due to the Favero bearings. They are smooth as hell, meaning that the pedal spins like crazy. Initially, I found that getting my cleat in position to engage the pedal was slightly more challenging than with my old SPD-SL Pedals, which just seemed to always be on the right position. Anyway, after a few rides, I got used to this.
As for the cleats, I have 2 pairs of shoes, one fitted with the red Xpedo Cleats that shipped with the pedals, the other using Look Keo Grip 4.5°. Both sets of cleats work, but I’d say that the Xpedo cleats have marginally better engagement/disengagement.
Lastly, the couple of times I contacted Favero support for advice, they were on the ball
