Wheels Manufacturing Derailleur Hanger 23 (GT, Jamis, Schwinn)

What Is It?

The Wheels Manufacturing Derailleur Hanger 23 is a precision-machined replacement derailleur hanger designed for selected GT, Jamis, and Schwinn bicycle models. The derailleur hanger serves as the connection point between the rear derailleur and the bike frame, while also acting as a sacrificial component that bends or breaks during impacts to protect the frame and drivetrain.

Wheels Manufacturing is well known for producing high-quality CNC-machined replacement hangers that often exceed the durability and accuracy of many original equipment hangers.
