Silca Announces New Titanium–3D–printed Derailleur Hanger

Indianapolis / Amsterdam – 12/09/23– Silca announces today its newest Titanium 3D printed product, the derailleur hanger. Improving stiffness in the shifting system, this product has already won Tour de France stages and resisted crashes, the ultimate sign-off by any pro cyclist and team.  Initially will be offered in fitment for Shimano DirectMount across 9 brands of frame as well as both UDH and UDH Direct Mount.  Additional models will be added based on demand.

This project was initiated by WorldTour teams, who for years have been making custom hangers from steel or higher-grade aluminum alloys in an attempt to improve durability and shifting performance. 

Modern electronic derailleurs shift so fast and with such force that conventional hangers made from low-grade aluminum plates will flex up to 4 degrees during a shift, resulting in less precise, noisier, and slower shifting.  Traditional hangers also bend easily, even in minor incidents, resulting in unnecessary bike changes and additional workload for mechanics.

Using advanced 3D modeling with AI-generated structural infill, SILCA 3DP Hangers for SRAM and Campagnolo fitment are 5-6x stiffer than aluminum hangers and 2-6 grams lighter (depending on the model).

For Shimano Direct Mount compatibility, the SILCA 3DP Direct Mount Hangers offer 8-10x higher stiffness with 4-12 gram weight savings by eliminating the use of the direct mount link from the assembly.

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 can 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 impacts.

SILCA 3DP Hangers will initially be offered in 11 different versions that cover 9 of the top bike manufacturers as well as UDH and UDH direct mount.

• Improved shifting speed and precision with reduced noise

• Reduced need to align hanger or adjust derailleur after minor impacts

• 2-12 gram weight savings depending on model and fitment

• Frame-saving fracture notch design allows the hanger to become sacrificial under the hardest of impacts

SILCA was founded in 1917 by Felice Sacchi outside of Milan, Italy, and was well-known for being the first company to put gauges on pumps, the first to produce a true ‘high-pressure’ frame pump, and the first to work with revolutionary lightweight material plastic after the end of WWII, and later the first to bring CO2 to roadside inflation. Today SILCA is located in Indianapolis, IN, where it continues to build iconic products that utilize the finest materials and craftsmanship available, while pushing technological boundaries by leveraging the most modern engineering and manufacturing practices and materials.
