Wolf Tooth Universal Derailleur Hanger - UDH

Wolf Tooth Universal Derailleur Hanger - UDH Info

Wolf Tooth Universal Derailleur Hanger - UDH is a precision CNC-machined replacement designed for frames built around the SRAM Universal Derailleur Hanger standard. By consolidating thousands of proprietary hanger designs into one universal interface, the UDH platform improves shifting alignment, simplifies replacement, and increases durability across modern road, gravel, MTB, and eMTB bikes.

This Wolf Tooth Universal Derailleur Hanger – UDH is an aftermarket upgrade to the stock hanger supplied with your frame. Built from full CNC aluminum construction, it offers robust strength and refined machining tolerances for consistent derailleur alignment. In the event of an impact, the hanger is engineered to rotate backward to help protect both the derailleur and frame from more serious damage.

For riders who value detail, bolts and washers are available in nine Color Shop anodized hues, allowing you to coordinate with other Wolf Tooth cockpit and drivetrain accents while maintaining a clean, professional finish.
