Wheels Manufacturing Derailleur Hanger 402 MFPN=910-21-370 shake well before usingWheels Manufacturing hangers are stiffer than almost any OEM hanger which improves durability and shifting performance.

Bicycle manufacturers may make mid year changes. Please use the hanger photos to select the proper hanger for your application. CNC machined 6061 aluminum Black anodized finish Made
