All my fault, I loaded my bike into the back of my car drive train down. I always cause my worst problems, at least I know who to blame. Anyway now my chain touches the cage at either the large or small chain ring, and it even touches the cage on the middle chain ring when on the rear cogs 2 in from the extremes. I tried adjusting the inner & outer limit screws and they don't go far enough and just make it so I can't shift onto the large ring. I've returned them to the original settings & can shift again. So I tried the barrel adjuster with no success. I really want to commute Monday and none of lbs near me are open or have wrenchs on Sunday. Anyone think they can talk me through this?
