Designed to be replaceable, the XLC derailleur hanger DO-A05 is a great alternative to your bike's original mech hanger when it's time to replace it. We've all had that moment where our bike's dropped on the drivetrain side, and we've rushed over to check everything is still working. The hanger has a key role to play in keeping your derailleur parallel to your frame and acts as a sacrificial component to keep your frame from bending or breaking. This particular hanger is suitable for city, trekking, mountain, road and race bikes and is made from lightweight aluminium. It's durable and contains two holes within with you can attach it to your bike frame and your rear derailleur.
