UDH Hangers (Universal Derailleur Hangers)


The UDH (Universal Derailleur Hanger) has quickly become the modern standard for derailleur mounting across performance road and gravel frames. Designed to improve compatibility, simplify replacement and protect drivetrain systems, UDH hangers are now widely adopted across leading frame platforms and drivetrain manufacturers.

At South Side Distribution, we offer a curated selection of UDH derailleur hangers from premium brands including Carbon-Ti and Nova Ride, alongside the standard SRAM-compatible option utilised on INNER Socializer framesets.

Our range includes both:

  • Standard SRAM UDH hangers

  • Shimano Direct Mount (DM) UDH hangers for Dura-Ace and Ultegra drivetrains

Each hanger is engineered to ensure precise derailleur alignment, which is critical for modern 11- and 12-speed systems where tight tolerances demand exact positioning. Premium CNC-machined options from Carbon-Ti and Nova Ride provide lightweight, high-strength alternatives for riders and workshops seeking refined drivetrain performance.

For bike shops building or servicing INNER Socializer titanium gravel bikes, UDH compatibility provides additional flexibility. When configuring a complete build, customers have the option to upgrade or customise their derailleur hanger, integrating Carbon-Ti or Nova Ride components into the final specification.

Supplied wholesale across Australia, including Melbourne, Sydney, Brisbane, Adelaide and Perth, South Side Distribution supports bike shops with a premium selection of UDH derailleur hanger replacements and upgrades, aligned to modern frame standards and high-performance drivetrain systems.
