Silca Titanium UDH Derailleur Hanger

The derailleur hanger is one of the most overlooked components on a modern performance bike — and on a bike equipped with fast-acting electronic shifting, a flex-prone aluminum hanger is actively working against you. SILCA's 3D-printed titanium UDH hanger is 5–7x stiffer than a standard aluminum hanger and 2–6 grams lighter, meaning every electronic shift command results in more precise, faster derailleur movement with zero wasted motion.

Using AI-generated structural infill and advanced 3D modeling, SILCA engineered stiffness exactly where the hanger needs it without adding unnecessary weight. An internal fracture notch allows controlled bending below the damage point in a crash, protecting your carbon frame. The hanger can also be hand-aligned after a minor impact, getting you back on the road or trail quickly. Already proven at the WorldTour level with stage wins at the Tour de France.
