SRAM Universal Derailleur Hanger (UDH)

SRAM Universal derailleur hanger
Specific for the McLaren Sport Electric Mountain Bike (McLaren Extreme does not require hanger)
The UDH is designed to optimize shift performance across all bikes as well as create a sensible solution for replacing damaged hangers. 
By standardizing the fixed position of the derailleur, the UDH creates a better and more consistent shift experience for all drivetrains and bikes.
It offers unparalleled derailleur protection. And perfect alignment. Guaranteed.
The UDH is designed to rotate rearward in the event of impact and features the ability to “re-rail” the chain back onto the small cog.
