Wolf Tooth | Universal Derailleur Hanger UDH

One small upgrade that quietly tightens up everything out back.

The Wolf Tooth Universal Derailleur Hanger UDH is a precision-machined replacement hanger for modern frames built around the SRAM UDH standard.

Designed for riders who want stronger construction and more consistent shifting than a stock hanger, this aftermarket UDH improves stiffness, durability, and alignment while remaining fully compatible with standard drivetrains. Compared to OEM hangers, Wolf Tooth’s CNC-machined approach delivers tighter tolerances, cleaner shifts, and a hanger that’s built to survive real-world riding and crashes.
