Hold on for 8 seconds!
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?
