UDH Derailleur Hanger—ultra-stiff titanium upgrade for flawless shifting
What Our Gearhead® Experts Are Saying:
"I swapped my stock UDH for this 3D-printed titanium version and immediately noticed tighter, smoother shifts—especially when climbing under power. It’s incredibly precise, easy to align by hand, and the added stiffness keeps my drivetrain perfectly dialed through chunky terrain and long rides."
We rely on consistent, precise shifting whether we’re grinding gravel or bombing enduro descents, and the UDH Derailleur Hanger delivers just that. SILCA’s 3D-printed titanium design uses advanced AI-optimized lattice engineering to increase stiffness while reducing weight compared to stock aluminum hangers. That added rigidity translates to crisper, faster shifts—exactly what modern drivetrains demand.
Compatible with both Shimano and SRAM setups, this UDH fits the universal standard while elevating performance for any bike using the system. The titanium construction offers 5 to 7x greater stiffness and drops a few grams, keeping your drivetrain aligned and responsive even after hard hits. A frame-saving fracture notch ensures the hanger gives way before your frame does, while the hand-alignable design makes on-trail corrections quick and tool-free.
