I have a new short cage X7 rear mech.
It wont shift down to the highest (i.e. the 11 tooth) cog on my cassette.
It just looks like it wont physically move far enough down. The limit screw is fully wound out so thats not stopping it. The cable is slack enough. Infact in the resting position with no cable, it wont go down far enough.
Mech hanger looks straight, it shifts into all the other gears fine.
Whats the problem?
This is the first sram mech Ive used, normally with shimano theres a large range of adjustment with the limit screws.
