Derailleur Hanger 403-RD

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 mech hanger 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.

Derailleur 403-RD has been designed to fit the Boardman SLR 9.8 Disc 2019, Boardman SLR 9.8 and Boardman SLR 9.6 2021-2024. If your Boardman bike has discs and a bolt through axle please check against this hanger. The hanger 403-MTB is different to this only in thickness where the rear mech fits. The 403-RD is thinner and allows the rear mech drop the chain onto the smallest sprocket on the cassette. The hanger 403-MTB does NOT allow this to happen and if in doubt please call us.

The image below shows the MTB hanger on the left which is thicker and the RD version on the right which is thinner.
