Thanks fellas , frustratingly it's going to be some time before I can ride it as finding an XC9000 group set is proving to be quite hard. I’ve found the easy parts but the roller cams, shifters are proving to be elusive and the front mech is another story… :roll: I think this might turn into one of the longest Wanted threads yet (hopefully not). Anyone got any idea what BB axle length these used? 122.5mm?
