The Universal Derailleur Hanger – or UDH – consolidates thousands of mountain bike derailleur standards.
- 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.
- The UDH works with all commercially available MTB and E-MTB drivetrains from Shimano to Box to Sunrace.
