For sale, brand new in box and unused. 172.55mm arms 110bcd. These can run normal round or Q Rings from Rotor and offer lots of flexibility in chainring sizes. Perfect if you go abroad and want compact gearing and then bigger gearing in the uk. Rotor make Q Rings from 50-53 (big ring) and from 34-38 (inner rings) that will all go on these crank arms.
Had these a while ready for a new project but decided to go for the 3d+ version istead as more copatible with new frame.
