Which could be from a bent hanger or not.
This would be my guess.
It seems many here like to dump on
LarrySellerz because of his posting history. In this particular case, we really don't who is to blame. If the hanger was bent, was it the shop that failed to check this or did the hanger get bent afterwards? Hangers can be bent quite easily, not just in a crash. If the bike falls on the DS, if someone taps the RD, the hanger can be bent. I had some a-hole on a club ride bump my RD with his front wheel which bent the hanger. I have also seen hangers get bent if there is a stiff chain link and the cage is pushed to its limit.
