Derailleur hanger
All models use the SRAM Universal Derailleur Hanger (UDH), S202600002. See the SRAM UDH Installation Manual for instructions.
Frames are compatible with either SRAM Transmission or standard drivetrains; however, a specific T-type chainring must be used that is compatible with the Turbo spider. Please contact an Authorized Specialized Retailer or Specialized Rider Care for assistance.
See the SRAM Chainlength calculator https://axs.sram.com/guides/chain/calculator for recommended chain length for T-Type transmission setup.
Grease should not be used on any part of the UDH.
Use caution when installing the UDH, 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.
