Gear Hangers – A rear mech derailleur hanger is a sacrificial part of a bicycle, designed to deliberately break in order to prevent damage to the main bike frame. Also known as derailleur hangers, gear mech hangers and frame-savers, a rear mech hanger is a relatively cheap and essential piece of equipment for anyone who is serious about their cycling.

A rear mech derailleur hanger is usually made of a relatively soft alloy which is either cast, stamped, forged or made using a CNC machine. It is attached to your bike using bolts or screws and then your rear derailleur itself bolts on to the hanger.
