I just got a MINT Trek 6000zx bike (easton frame) for free. I was moving the grip shift and broke the shifter.
I just bought a BRAND NEW Deore shift/brake combo on Ebay ($14). These are a 9 speed shifting system, can this be used on a 7 speed system.
I thought if a adjust the limit screws so the shifter would not try and through the chain, it would be ok.
Thank you for your time and effort
