Derailleur hanger
SRAM Universal Derailleur Hanger (UDH), S202600002
2023 S-Works and Pro complete bikes are built with the direct-mount SRAM Transmission drivetrain. Frames are compatible with either SRAM Transmission or standard drivetrains.
Grease should not be used on any part of the UDH.
Use caution when installing the UDH, as the bolt is left hand threaded. Avoid tightening the UDH bolt with a wheel is installed as this will increase the torque on the axle as well as the UDH bolt.
Mechanical rear derailleurs are compatible. See instructions in the user manual for cable routing.
