X-LAB RS5 Universal Derailleur Hanger (UDH) Protect your frame and restore precise shifting with the genuine X-LAB RS5 Universal Derailleur Hanger. The X-LAB RS5 UDH (Universal Derailleur Hanger) is the factory replacement derailleur hanger designed specifically for compatible RS5 road bike frames. Manufactured from durable 6061 aluminum, it is engineered to absorb impacts during crashes or tip-overs, helping protect both the frame and rear derailleur while maintaining accurate shifting performance. The Universal Derailleur Hanger (UDH) standard was developed to simplify replacement parts across the cycling industry while improving drivetrain reliability. Its rotating design helps reduce drivetrain damage by allowing the hanger to move rearward during impacts instead of transferring force directly into the frame or derailleur.  This genuine X-LAB replacement features an M12 × 1.5 interface and provides OEM fitment for compatible RS5 frames.
