I put on a 11-34 XT cog on my wife's 2004 feminine Jekyll and the top mech pully is hitting the 34 tooth. I can hear it and feel it when I ride, that's how bad it is. I tried to adjust the little screw but it didn't help that much. In the end I rigged it so it's running fine now but I'd like to find a better solution for the problem. I'm thinking maybe the hanger was designed for up to 32 tooth cog. Anyone have any ideas?

In some rear mechs the spring adjusted by the screw you mention have two positions: on my very old xtr this is accomplished by two holes in which the spring can be attached. I had the same issue and solved it this way. Unfortunately this means you need to disassemble the spring assembly and reassemble it can be tricky because the spring has to be preloaded.

Thanks for all the replies! Yes it's the B-Tension screw. It didn't help that much and I maxed it all the way in and then all out. I think I'll try the 10 tooth pully unless someone can explain way it won't work.

My wife's in the granny and 34 when it hits. I don't know about any other gears.
