• 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.
