Built from FACT 12r Carbon with Specialized's Rider First Engineered™ design, it applies the same breakthroughs that made Aethos the lightest bike ever to a dedicated gravel platform—a frame that climbs like a dream, floats over rough terrain, and weighs less than a full water bottle. With 47c\/650b x 2.1\" tyre clearance and race-influenced fit drawn from Crux's cyclocross heritage, this frameset is the ultimate foundation for a full custom gravel race build.\u003c\/p\u003e\n\n\u003ch3\u003eKey Highlights\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eUltra-lightweight FACT 12r Carbon frame:\u003c\/strong\u003e just 725 grams (size 56)—the lightest gravel frame in the world, without sacrificing the stiffness needed for hard efforts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMassive tyre clearance:\u003c\/strong\u003e 47mm on 700c wheels or 2.1\" on 650b, giving Diverge-level capability in a race-focused frame.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUDH derailleur hanger:\u003c\/strong\u003e Universal Derailleur Hanger compatibility means the frame is ready for the latest SRAM Transmission drivetrains.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRider First Engineered™ geometry:\u003c\/strong\u003e each frame size is individually tuned for a consistent, race-ready ride feel across the size range.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete frameset package:\u003c\/strong\u003e includes the matching S-Works FACT Carbon fork, threaded headset with carbon top cap, and Roval Alpinist Carbon seatpost—everything needed to build up a full custom race bike.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame:\u003c\/strong\u003e S-Works Crux FACT 12r Carbon, Rider First Engineered™, threaded BB, 12x142mm thru-axle, flat-mount disc, UDH dropout, 725g (size 56)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFork:\u003c\/strong\u003e S-Works FACT Carbon, 12x100mm thru-axle, flat-mount disc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeadset:\u003c\/strong\u003e Threaded, cartridge bearings, carbon top cap included\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBottom Bracket:\u003c\/strong\u003e Threaded BSA shell\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeatpost:\u003c\/strong\u003e Roval Alpinist Carbon, integrated wedge-style seat collar\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax Tyre Clearance:\u003c\/strong\u003e 47mm (700c) or 650b x 2.1\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Hardware:\u003c\/strong\u003e Headset bearings and carbon top cap\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSizes Available:\u003c\/strong\u003e 49, 52, 54, 56, 58\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Specialized","offers":[{"title":"Nebula Metallic\/Quartz Metallic \/ 49","offer_id":53266152194411,"sku":"71426-0149","price":6499.99,"currency_code":"AUD","in_stock":true},{"title":"Nebula Metallic\/Quartz Metallic \/ 52","offer_id":53266152227179,"sku":"71426-0152","price":6499.99,"currency_code":"AUD","in_stock":true},{"title":"Nebula Metallic\/Quartz Metallic \/ 54","offer_id":53266152259947,"sku":"71426-0154","price":8200.0,"currency_code":"AUD","in_stock":true},{"title":"Nebula Metallic\/Quartz Metallic \/ 56","offer_id":53266152292715,"sku":"71426-0156","price":6499.99,"currency_code":"AUD","in_stock":true},{"title":"Nebula Metallic\/Quartz Metallic \/ 58","offer_id":53266152325483,"sku":"71426-0158","price":6499.99,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0912\/6241\/9307\/files\/71426-01_CRUX-SW-FRMSET-NBLMET-BDXMET-QTZMET_HERO-SQUARE.jpg?v=1779360154","url":"https:\/\/spokentrail.com.au\/products\/crux-sw-frmset-4223486","provider":"Spoke N Trail","version":"1.0","type":"link"}
