• 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.

* note, the UDH is not a unversal hanger solution for ALL bikes.
