Derailleurs hangers, mech hangers, mech dropouts, cast hangers, road bike hangers, mountain bike hangers and hanger dropouts are different names for the same bike components. Derailleurs are essentially small pieces of metal that are attached to the rear frame of your bike and are designed to absorb any impact and strain that would be focused on the frame of the bike, they will bend or break off to protect the main body of the frame.
