Chain is riding up on casette and shifting inconsistently it's winding me right up! I've tried adjusting the mech till I'm blue in the face. Tried taking the chain off and degreasing and checking for stiff links and twists of which there was none. Changed the mech hanger. Cleaned and lubed the mech. Swore at it, etc. It always seems to end up riding up on the top 2 rings, and also doesnt shift up or down well in the mid range. The cables are about 3 or 4 10 mile rides old and seem to move in and out fine.
