do I need to cut off the FD bracket?
I'm converting a vintage steel frame to new drive train...and need some advice on how to deal with the front derailleur.
It currently has a braze-on Campy Record FD, meant for a 52/42 crank. I would like to use a compact 50/34, but even with the FD slid down to the lowest possible position, it can't grip the chain securely enough to upshift, without launching the chain over the outside of the big ring.
A braze-on Shimano Ultegra FD 6700 is readily available. The question is, what is the distance from the center of the crank to its proper position?
Presently, where the FD mounting bolt hits the bottom of the braze-on slot, it is about 145mm from the center of the crank.
Will the 6700 work? if not, is there another FD that might fit...or do I need to cut off the bracket?--or just give up on the compact crank?
