Product Overview
The M Part Universal SRAM UDH Gear Hanger is a practical replacement or spare hanger for riders using a UDH-compatible frame. The SRAM Universal Derailleur Hanger standard was developed to simplify derailleur hanger compatibility across modern bicycles while maintaining accurate derailleur positioning and helping protect the drivetrain during impacts.
Manufactured from cold-forged 6061 aluminium, the M Part UDH hanger is engineered with the appropriate hardness to provide reliable support for the rear derailleur while still allowing the hanger to deform during a significant impact. This sacrificial design can help prevent more costly damage to the bicycle frame or derailleur.
Ideal to keep in your workshop, toolbox or bikepacking spares kit, this hanger is compatible with frames specifically designed for the SRAM UDH standard. Always confirm that your bicycle frame is UDH compatible before installation.
