The Universal Derailleur Hanger, designed by SRAM, simplifies the never ending array of derailleur hangers that we’re all just subtly different into a single unified design, making it easier for you and bike shops to always have a spare available.

Our U.D.H. makes it even better by precision machining it from 6061 aluminum. Modern drivetrains are precise and exacting and deserve to be mounted to a derailleur hanger of equally precise quality. The Robert Axle Project Universal Derailleur Hanger is made to the exact same geometry as the stock SRAM hanger ensuring a perfect fit to your bike and any drivetrain you’d like to mount to it.
