When I am in the smallest chain ring and the largest cog in the back, I have < 1 mm of clearance. Which I understand is the idea.
When I am on the largest chain ring, I have well over 1 mm of clearance. As I understand it, I am supposed to use the H limit screw to bring the cage in lower to the chain.
HOWEVER, and here is the problem, the H limit screw is all the way in there! It won't turn no more?! No what? I've had the chain jump off to the outside of the chain ring at least a few times now. Pretty annoying.
