SILCA - 101 Derailleur Hanger

SILCA 3D-printed titanium derailleur hanger 101 brings precision engineering to one of the most overlooked components on a performance bicycle. Modern electronic derailleurs shift with speed and force that exposes the weakness of standard aluminum hangers — conventional plate hangers flex up to 4 degrees during a shift, undermining the precision that electronic shifting systems are designed to deliver. Using AI-generated structural infill and advanced 3D modeling, the SILCA 101 hanger is 2–7x stiffer than an aluminum equivalent while being 2–6 grams lighter.

Already proven at the WorldTour level — including stage wins at the 2023 Tour de France — and credited with maintaining derailleur alignment through race-day crashes. An internal fracture notch allows the hanger to fail safely below the point of frame contact, protecting carbon frames under the hardest impacts. Hand-alignable after minor bends.
