I have an ultegra 6600GS rear mech, but it is not capable of going larger than a 30T highest cog, I tried.
what part number XT mech did you use?
is it a shadow+ mech?
in another thread I was also told the new XT stuff has changed ratio of cable mm/movement, if someone knows this exact info of before and after I'd love to know as I REALY want a shadow+ neck for the clutch chain tension on the canal tow paths.
