How to choose a replacement rear mech derailleur hanger for a carbon, aluminum or titanium alloy frame

Take a spare removable derailleur hanger with you!

Most modern bicycles are equipped with an external rear derailleur system. The rear derailleur is the most vulnerable part of this system. If it is overloaded, the bike frame or the rear derailleur itself may fail. Frames made of aluminum, titanium alloys, carbon are not repairable or require a lot of time and financial investments.

For safety reasons, a fuse is provided in the frame design - a removable derailleur hanger. This is a small derailleur hanger or mech hanger that attaches the rear derailleur to the frame.

There are numerous names (definitions) for bicycle derailleur hanger or mech hanger: rear mech derailleur hanger, gear hanger, derailleur hanger, gear mech hanger, removable derailleur hanger, mech hanger, sos hanger, frame saver, removable dropout, rear derailleur mount  and others.

The design, shape and material of the derailleur hanger or mech hanger are designed to ensure that this particular derailleur hanger will break in the event of an accident or mechanical failure. To restore the bike, it is enough to replace an inexpensive broken derailleur hanger.
