UDH Direct Mount 3DP Titanium Derailleur Hanger

Silca UDH Direct Mount 3DP Titanium Derailleur Hanger upgrades a compatible UDH-equipped frame with a 3D-printed titanium hanger designed to increase drivetrain rigidity for more consistent shifting, while still protecting the frame in a crash. The direct-mount layout is built to replace the B-link interface on compatible Shimano rear derailleurs—an increasingly relevant detail as newer Shimano XTR and XT derailleurs may not include a B-link in the box.

• 3D-Printed Titanium Construction - Higher stiffness potential than conventional hangers for a more stable derailleur position under load and rough terrain
• High-Stiffness Design - Silca reports up to 12x the stiffness of typical stock aluminum hangers, helping reduce hanger flex that can show up as inconsistent shifting
• Direct-Mount Compatibility - Replaces the B-link interface on compatible Shimano rear derailleurs for a cleaner, more rigid mounting solution
• Frame-Saving Fracture Notch - Engineered to be sacrificial in severe impacts to help reduce the chance of frame damage
• Weight-Conscious Upgrade - Reported to be 2–10 g lighter than many stock aluminum hangers, depending on the original hanger
• Axle Fit Requirement - Designed specifically for frames using 12 x 1.0 thru axles
