UDH Derailleur Hanger

What Our Gearhead® Experts Are Saying:

"The SILCA UDH hanger is the real deal. It’s stronger, stiffer, and lighter than any aluminum model I’ve used. The difference in shifting precision is obvious, especially under load with electronic derailleurs. It’s also the only hanger I trust to protect my frame if things go sideways."

Engineered for riders who demand precision, the SILCA 3D-printed titanium UDH Derailleur Hanger redefines what a small component can do. Constructed using aerospace-grade additive manufacturing and AI-optimized infill, it’s up to 12 times stiffer and several grams lighter than standard alloy hangers. That stiffness translates directly into faster, cleaner shifts—critical when running high-torque electronic derailleurs that can expose the flex in conventional mounts.

Beyond pure performance, SILCA’s thoughtful safety engineering includes a built-in fracture notch designed to absorb impact energy and protect the carbon frame during hard crashes. The hanger’s micro-aligned fit allows for manual adjustment without tools, maintaining drivetrain precision even after minor tip-overs.

Whether used on a road race bike or a modern trail machine, the SILCA UDH Derailleur Hanger pairs unmatched stiffness with thoughtful crash protection—bringing pro-level drivetrain precision to every ride while preserving the longevity of your frame.
