Anyone know the pull ratios of Zee 10sp and XT 9sp Mechs? I'm putting a bike together from a load of spares and I'm having difficulty getting a shifter and derailleer to play well. I think the problem is the Zee mech. Does anyone know the pitch/pull ratio in MM of the XT shifter compared to the Zee shifter? Ideally an answer 'from the horses mouth' would be good as I've read all sorts of conflicting info.
Shimano’s Dyna-Sys (10 speed MTB) products are only compatible with components in the Dyna-Sys lineup, from XTR to SLX. They are not compatible with any other parts. Use of a Dyna-Sys derailleur with 9-speed shifters is contraindicated.
