People see #Silca 3D printed titanium derailleur hangers and assume it's a weight weenie type product. Another place to shave a gram. That is not why we created this product. Titanium derailleur hangers bring increased strength and stiffness to this overlooked component so critical to quick and precise shifting. 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 3DP Hangers are 2-7x stiffer than aluminum hangers while also being 2-6 grams lighter depending on model. Lastly, they feature a fracture notch, designed to save your frame during hard imapcts or crashes.
