SILCA 3DP TI Standard Hanger | Trek

Improve your shifting performance with a new derailleur hanger that is up to 12x as stiff as the stock aluminum hanger and 2-6g lighter.

SILCA 3D printed 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.

Already in use at the World Tour level SILCA 3DP Hangers were utilized in 2 stage wins of the 2023 Tour de France and are credited with maintaining derailleur alignment across numerous crashes.

SILCA 3DP Hangers are able to be aligned by hand, and are designed with an internal fracture notch which allows the hanger to fracture and bend below the point of damage for the carbon frame to eliminate the risk of frame damage under the hardest of impacts.

Features

• 5-7x stiffer
• 2-6g lighter
• Improves shifting performance
• Reduced risk of minor hanger mis-alignments after crashes
• Frame saving fracture notch design allows the hanger to become sacrificial under the hardest of impacts

Note: These hangers are compatible with most derailleur systems. For direct mount Shimano hangers, we the DM variant of this hanger.
