What is a derailleur?
+
Derailleurs shift your chain at the rear sprocket. They are fitted with limit screws which keep it from shifting too far in or out.
What do I do if my derailleur gets bent?
+
Usually the hanger is what bends, not the derailleur itself. You can purchase derailleur alignment tools to help you straighten a bent hanger if you don't want to take your bike to a shop.
