Derailleur Hanger 315

Derailleur Hanger 315 is a precision-engineered component designed to protect your Cube bike frame while ensuring smooth and accurate gear changes. Also known as a mech hanger, gear hanger, or mech dropout, a derailleur hanger is a small metal component mounted to the rear of your bike. Its main function is to absorb impact and strain, bending or breaking in the event of a crash or derailleur misalignment to prevent damage to the frame.

This Cube derailleur hanger has been specifically designed to fit a range of Cube bike models, providing correct derailleur alignment and reliable shifting performance. It’s a robust, premium, yet affordable upgrade over standard cast hangers, giving riders confidence and reassurance on every ride.
