On my Tomac 204, I ran a road cassette (27 top gear I think) with a Dura Ace rear der. and XT trigger. All 9 speed. Worked fine
I transferred all the parts to my Mountain Cycle 9.5 but switched the cassette to a 32T max. At first, I had trouble shifting into the lowest 2 or so gears. I figured i was the chainguide so I spaced it out and it was better but I still had issues. Now, the lowest 3 do not work properly (in the third it gets there but skips, cannot get to the lower 2 at all). It's not the limit scew (I took it out and the problem persisted) or the tension (downshifts on the first click). Adding b-tension does nothing.
I replaced the der with a 105 thinking something maybe was bent (still short cage) and now the highest gear does not work (der does not reach it, no matter where the limit is and with no cable tension at all). The der also does not reach the lowest gear (the shifter shifts to it but the der doesn't move; in the shifter, it feels the way it would if the limit was too far in....but the limit screw isn't changing anything).
I am sure I am turning the right scews. The hanger appears perfectly straight. I took the wheel out (12x135mm), checked it, made sure the cassette was tight and reinstalled.
Any ideas?
