As above a clutch type rear mech that will work with a old 9 speed shifter
These new modern clutch mechs are all 10 / 11 speed
Has anyone got one to work successfully with less gears
I did read a thread somewhere online about taking the clutch part off a 10 speed and fitting to an m972 shadow rear mech. Might be worth a Google as I can't remember where I read this.
