WHEELS MANUFACTURING Derailleur Hanger - 131 Orange Seal 68 durometer center ridge forWheels 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. These hangers DO NOT INCLUDE attachment hardware
