Thanks, wouldn't have thought of that. Since I'm having problems on the downshifting, maybe bending out a few of the inner rings teeth would help. I was also thinking I could maybe put some bumps of jb weld or something on the inside of the outer ring to push the chain over onto the small ring better. It would be nice not to risk messing up the rear shifting with a thicker chain.
