Options for a new FD boss on my carbon frame?
I recently put a new Campy drivetrain on my old carbon Kestrel 200sc. The only problem is that the 'braze-on' front derailleur boss holds the FD too far out from the centerline of the bike, causing chain rub in my lowest 3 gears.
Obviously, I need to move my derailleur in towards the centerline of the bike, but this is complicated by two things:
1. The seat-tube isn't round, meaning I can't use a braze-on clamp adapter.
2. I'm not sure where to find Campy-compatible FD bolt-on bosses.
Anybody got any ideas on how to solve either of the above issues?
