Listed are Ultra torque cups for Campagnolo Chorus, Record or Super record ultra torque chainsets. Note older veloce, centaur and athena chainsets were of the Ultra torque type as well and these cups are suitable replacements.
For replacing bearings you need the ultra torque bearing kit. You have to remove the NDS and DS bearing from the crankarm and press on new bearings. If you need help give the shop a call.
