9 speed shifting problem
I have two 3x9 speed bikes, both mountain. One shifts perfect, one doesn't like the 4th from the bottom cog and shifts past it every time on the stroke up or down. swapped wheels and the problem shifted bikes swapped cassettes and the problem stayed with the XT CS M750 9 speed cassette. (used when it came to me) what are the odds that someone respaced it for other than mountain use?
