A bent derailleur hanger can quickly compromise shifting performance and, if left unchecked, lead to unnecessary drivetrain wear. The Ribble ULTRA TT Caliper Mech Hanger is a genuine replacement part, precision-machined to restore accurate rear derailleur alignment and smooth, dependable gear changes.

Designed exclusively for the ULTRA TT and ULTRA TRI rim brake frames, this sacrificial hanger is engineered to absorb impact before damage reaches the frame. Whether you're replacing a worn hanger or carrying a spare for race day, it's a simple upgrade that helps keep your bike performing at its best.

Derailleur hangers are designed to be sacrificial components. Engineered to bend or break under impact or excessive force, they help protect your bike frame and rear derailleur from more costly damage.
