{"product_id":"derailleur-hanger-103","title":"SILCA - 103 Derailleur Hanger","description":"\u003cp\u003eSILCA 3D-printed titanium derailleur hanger 103 brings precision engineering to one of the most overlooked components on a performance bicycle. Modern electronic derailleurs shift with speed and force that exposes the weakness of standard aluminum hangers — conventional plate hangers flex up to 4 degrees during a shift, undermining the precision that electronic shifting systems are designed to deliver. Using AI-generated structural infill and advanced 3D modeling, the SILCA 103 hanger is 2–7x stiffer than an aluminum equivalent while being 2–6 grams lighter.\u003c\/p\u003e\n\u003cp\u003eAlready proven at the WorldTour level — including stage wins at the 2023 Tour de France — and credited with maintaining derailleur alignment through race-day crashes. An internal fracture notch allows the hanger to fail safely below the point of frame contact, protecting carbon frames under the hardest impacts. Hand-alignable after minor bends.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e3D-printed titanium — 2–7x stiffer than aluminum hangers\u003c\/li\u003e\n\u003cli\u003e2–6 grams lighter than aluminum equivalents\u003c\/li\u003e\n\u003cli\u003eAI-generated structural infill for optimal stiffness distribution\u003c\/li\u003e\n\u003cli\u003eInternal fracture notch protects carbon frames in crashes\u003c\/li\u003e\n\u003cli\u003eHand-alignable after minor impacts\u003c\/li\u003e\n\u003cli\u003eCompatible with Shimano and SRAM rear derailleurs\u003c\/li\u003e\n\u003cli\u003eProven at WorldTour level\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Silca","offers":[{"title":"Shimano","offer_id":40491435163711,"sku":"AM-AC-056-ASY-0103","price":85.0,"currency_code":"USD","in_stock":false},{"title":"SRAM","offer_id":40491435196479,"sku":"AM-AC-056-ASY-0203","price":85.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0768\/3539\/products\/SILCA103_1_1.jpg?v=1709665823","url":"https:\/\/thegearattic.com\/products\/derailleur-hanger-103","provider":"The Gear Attic","version":"1.0","type":"link"}
