My 4iiii's on the Tarmac, Shimano 105. Shimano Cues on my Diverge. I don't ride my Motobecane much anymore but for commuting and then it's not for longish rides. It's fitted with a Stronglight 93 triple in it's current iteration.

Last time I checked 4iiii wasn't doing retrofits. That may have changed since, I'll check that out.

Still, having a pair of pedals I can swap between bikes is an attractive aspect.

Bouncing this topic off Google tells me "The Assioma Pro RS and DUO-Shi models are designed specifically for Shimano SPD-SL cleats, while the original Assioma Duo/Uno use Look Keo cleats."

AND that I can slip Shimano R7000 pedals onto Assioma spindles. Seems there's more out there I need to look into....
