Bicycle half producer Silca is introducing its latest titanium 3D printed product, the derailleur hanger. Bettering stiffness within the shifting system, this product has already received Tour de France levels and resisted crashes, the final word sign-off by any professional bike owner and crew. Initially, it will likely be supplied in fitment for Shimano DirectMount throughout 9 manufacturers of body in addition to each UDH and UDH Direct Mount. Extra fashions can be added primarily based on demand.
This isn’t the primary Silca 3D printed product nevertheless it’s definitely the one that’s going to generate bigger manufacturing necessities, with a number of totally different fashions already accessible. Whereas it ensures elevated energy and stiffness to this typically ignored part, so vital to fast and exact shifting, one of the crucial attention-grabbing features is that it prices similar to historically manufactured ones of comparable high quality.
This undertaking was initiated by WorldTour groups, who for years have been making customized hangers from metal or higher-grade aluminum alloys in an try to enhance sturdiness and shifting efficiency. Trendy digital derailleurs shift so quick and with such drive that standard hangers from low-grade aluminum plates flex as much as 4 levels throughout a shift, leading to much less exact, noisier, and slower shifting. Conventional hangers additionally bend simply, even in minor incidents, leading to pointless bike adjustments and extra workload for mechanics.
Utilizing superior 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 (relying on the mannequin). For Shimano Direct Mount compatibility, the SILCA 3DP Direct Mount Hangers provide 8-10x greater stiffness with 4-12 gram weight financial savings by eliminating using the direct mount hyperlink from the meeting.
Already in use on the World Tour stage, SILCA 3DP Hangers had been utilized in 2 stage wins of the 2023 Tour de France and are credited with sustaining derailleur alignment throughout quite a few crashes. SILCA 3DP Hangers might be aligned by hand and are designed with an inner fracture notch, which permits the hanger to fracture and bend beneath the purpose of harm for the carbon body to remove the danger of body injury beneath the toughest impacts.
SILCA 3DP Hangers will initially be supplied in 11 totally different variations that cowl 9 of the highest bike producers and UDH and UDH direct mount. Advantages embody improved shifting pace and precision with decreased noise, a decreased must align hanger or alter derailleur after minor impacts and 2-12 gram weight financial savings relying on mannequin and fitment. A frame-saving fracture notch design permits the hanger to turn into sacrificial beneath the toughest of impacts.
