#Silca 3D printed titanium derailleur hangers bring increased strength and stiffness to this overlooked component. Modern electronic derailleurs shift so fast, and with such force, that conventional hangers made from low grade aluminum plate will flex up to 4 degrees during a shift resulting in less precise and slower shifting. Using advanced 3D modeling with AI generated structural infill, Silca Hangers are 2-7x stiffer than aluminum hangers while also being 2-6 grams lighter depending on model. Oh they look pretty neat too and we have UDH options!
