When ultrashift first came out you could get repair parts, but that didn't last long because there is simply not much to wear out.

I rode Campy 10 speed triples for many years. As I remember there was no micro ratcheting. There was a position for each chain ring and the ability to trim the derailleur to the right. I later switched to a compact double crank with Campy 11. I'm still using my old 10 speed medium cage RD with 10 speed ultrashift levers, converted to 11 speed with two parts from a wreck damaged 11 speed lever. In the early days of ultrashift the Centaur 10 speed levers came with carbon fiber brake lever, just like Record, but labeled as Centaur.
