I have just bought a triple front mech for my steel touring bike but the clamp is waay too big- anyone got any shims or suggest something- seat post dia is 27.2 so guessing seat tube dia is 28.6 (from late research) the mech may even be 34.9. I know this is a big gap so would I be best getting the right size and selling the mach I have?
cheers
