I bought a new frame and put my old Campagnolo Racing T components on it. The seat tube has a diameter of 35mm and I use the Campagnolo 35mm clamp for the Racing T derailleur.
The problem is the derailleur can't push the chain to the small gear because a part of the derailleur touches the seat tube.
Is the frame incompatible with a 3 speed crank or do I just need a compatible derailleur for frames with a wider seat tube, maybe the ATHENA Tripple?
