Derailleur Hanger 404

Derailleur hangers are the least attractive thing to go on a bike and we never really think of stocking up on them until they break, but it protects the frame of your bike. Derailleur hangers have many names such as mech hangers, mech dropouts, cast hangers, mountain bike hangers and hanger dropout (the list is endless). Each mech hanger is designed to either bend or snap, to prevent any damage being done to the main body. It is always recommended to carry a spare derailleur as they can bend or snap at any given time. Once snapped, the bike can’t be ridden otherwise you’ll cause more damage to the bike.

All of our rear mech hangers have superior strength, amazing durability and great shifting, which makes this your premium yet affordable upgrade from a standard cast hanger. Derailleur 404 has been designed to fit some Trek bike models
