Hi Looking at getting a Chorus rear mech onto my 90s colnago build, my wheels have 9 speed cassette already so I'm wondering how to check if a second hand Chorus Mech is 9 speed as well , some advertised say 8 speed, but what is the difference ?? I will be using Campag C Record friction shifters, (ie not indexing) ?? Any advice welcome ?
