Wheels Manufacturing Derailleur Hanger 399

Wheels Manufacturing hangers are stiffer than almost any OEM hanger, which improves durability and shifting performance.

• OEM hangers are only produced by a handful of manufacturers, mostly in Taiwan and China. As a result, you will see many bikes with exactly the same hanger. Bicycle manufacturers may make mid year changes. Please use the hanger photos to select the proper hanger for your application.
