Yojimbo_ said:I have a LOOK 565 frame, and it's clamp on for the front derailleur.
Given a choice, I want the clamp on because if I ever install a compact crank, it will be a very simple matter to lower the clamp to compensate. Not sure how to do this with a braze on.
All Braze-on attachments allow a wide range of adjustable vertical possitions within the attachment. It is very easy to move them up and down.
