WAG Universal Derailleur Hanger (UDH)
The WAG Universal Derailleur Hanger is a replacement hanger for bicycle frames designed around the UDH standard. UDH simplifies derailleur-hanger replacement by using a common mounting design across a growing number of mountain bikes, e-MTBs and road bikes.
Correct hanger alignment is essential for accurate shifting, particularly on modern wide-range drivetrains. Replacing a bent or damaged hanger can help restore consistent gear changes and proper rear-derailleur positioning.
Important Frame Compatibility
“Universal” refers to the standardised UDH design—it does not mean that this hanger fits every bicycle. The frame must be specifically manufactured to accept a UDH-type hanger.
Before purchasing, check the existing hanger, bicycle manufacturer’s specifications or frame documentation to confirm UDH compatibility.
Broad Drivetrain Compatibility
When fitted to a compatible UDH frame, the hanger can be used with commercially available rear derailleurs from brands including Shimano, SRAM, Box and SunRace. Compatibility is determined primarily by the bicycle frame’s hanger interface rather than the drivetrain brand.
Accurate Derailleur Positioning
The hanger provides a secure and correctly aligned mounting point for the rear derailleur. This helps support smooth shifting and reduces the risk of poor gear performance caused by a bent or incorrectly positioned hanger.
