I adjusted the indexing cable to wrong direction, ended up getting the derailleur stuck in the wheel and bent off. I am a moron, I know.
Now, I obviously need to replace the derailleur hanger, how about the chain and can you see any damage on the rest of the derailleur? The pulleys spin just fine, cable seems fine. Is there any specific damage I should look for?
Sorry, which part Is the derailleur arm(s)? When I previously said the arm broke I meant the hanger. The hanger is the part that snapped in half.
