I have a 1987 Eddy Merckx Century frame. I'm installing campy chorus triple 10 speed crank (53/42/30 chainrings), and bought a centaur 10 speed triple braze on front der.
The problem is that the der. Cage does not clear the large chain ring even when set at the top of the braze-on slot. The overlap is approx. 4 mm. There is no way a little filing will create the room needed.
The der. Looks identical to the other braze on 10 speed front der I have seen.
Any ideas or suggestions?
Thank you in advance!
