CNC Machined Aircraft Grade Aliminum UK Made


A derailleur hanger, otherwise known as a mech hanger, mech dropout, cast hanger, mountain bike hanger and hanger dropout is a piece of metal that is attached to the rear axle of a bike. The main job of a derailleur is to adsorb any strain, resulting in either snapping or bending to protect the frame of the bike. This helps prevent any damage being done to the frame of the bike, which can become costly when damaged. It is always recommended that cyclists carry a spare derailleur with them wherever they go, as these can break at any given time causing an inconvenience.

We boast over 400+ CNC machined mech hangers, all of which are made from 6082 T6 aluminium and all come in a classic black anodised finish, which is perfect for all types of bikes. Our team work hard to make sure all of our cast hangers are manufactured to the best quality. All of our derailleurs have superior strength, amazing durability and great shifting, making this a robust upgrade from your standard rear mech dropout. All derailleurs are designed and manufactured in the UK, Stoke-on-Trent.
