I've put together a 10 speed campag chorus groupset but cannot index the middle sprockets on the cassette the chain always slips here. Only thing not new are the chainrings. Any ideas?
this is not a very helpful response, but I had a similar issue with a new shimano 10 speed drivetrain recently. After riding it a bit, the issue went away. someone suggested to me that the mech hanger might be out of line. I never checked it though as it's fine now.
Unfortunately I've tried that option. Running through all the gears again I've noticed that I'm going from one end of the casette to another with 8 shifts instead of 9.
