Silca 105 Specialized Derailleur Hanger

SILCA 3D printed titanium derailleur hangers deliver the stiffness and precision demanded by modern electronic shifting. Conventional aluminum hangers flex up to 4 degrees during shifts, compromising speed and accuracy. SILCA 3DP Hangers are 5–7x stiffer than aluminum while weighing 2–6 grams less, thanks to AI-generated structural infill and advanced 3D modeling. For Shimano Direct Mount systems, these hangers achieve 8–12x higher stiffness with 4–10 gram weight savings by eliminating the direct mount link entirely. Already proven at the World Tour level—including 2 stage wins at the 2023 Tour de France—SILCA 3DP Hangers maintain derailleur alignment through crashes and rough terrain. Hand-alignable and engineered with an internal fracture notch, these hangers bend or fracture below the damage point, protecting your carbon frame from impact damage. A critical upgrade for riders demanding precision and durability.
