{"product_id":"specialized-s-works-crux-5-frameset","title":"Specialized S-Works Crux 5 Frameset","description":"\u003cp\u003eThe Specialized S-Works Crux 5 Frameset is engineered for elite gravel racers who demand the fastest foundation ever created for race-winning performance. Built around Specialized's Time to Finish philosophy, a physics-based metric that optimizes total elapsed race time over real-world courses, this frameset translates more of your effort into pure speed across challenging gravel terrain. When the goal is the top step, no gravel frameset gets you there faster.\u003c\/p\u003e\n\u003cp\u003eConstructed with FACT 12r carbon, the S-Works Crux 5 frame weighs just 789 grams and represents one of the lightest gravel frames in the world while maintaining the stiffness and compliance targets proven on the universally loved Crux 4. The revolutionary Flow State Design emerged from engineers studying frame behavior under load, discovering that frames weren't just 'breathing' under stress. By optimizing tube shapes instead of adding material, Specialized eliminated unnecessary carbon layers, resulting in a lighter frame with better ride quality and improved structural integrity. The 789-gram FACT 12r frame withstands over 100,000 cycles at 2,377 watts, far beyond industry standards.\u003c\/p\u003e\n\u003cp\u003eEvery tube has been precisely sculpted for speed at elite gravel races, drawing directly from Tarmac SL8 learnings to achieve 15.2 watts of aerodynamic advantage at 45 kph without compromising weight. The FACT 12r carbon fork pairs with the frame to deliver unparalleled handling precision and responsiveness. Rider-first engineering ensures that every size from 49–61cm receives a specific layup based on performance metrics unique to that size, delivering consistent stiffness, compliance, and handling regardless of rider height. Progressive geometry includes a slacker head angle for increased confidence at speed, steeper seat angle for more efficient power position, longer size-specific reach for improved balance, and lower BB height for stability with big tires.\u003c\/p\u003e\n\u003cp\u003eThe frameset accommodates up to 55mm tires without any compromise, lighter weight, more aerodynamic, better handling, and the ability to run the right tire for any course while maintaining full aerodynamic efficiency. Real-world validation using Specialized's Moving Leg Mannequin (sixth generation) proves that S-Works Crux 5 would save elite rider Sofía Gómez Villafañe over 9 minutes 58 seconds at Unbound purely through equipment efficiency.\u003c\/p\u003e\n\u003cp\u003ePerfect for competitive gravel builders seeking the lightest, most aerodynamically optimized frameset ever made, the S-Works Crux 5 delivers progressive geometry with balanced handling, telepathic steering response, and proven engineering that makes it race-ready from day one.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame - \u003c\/strong\u003eFACT 12r Carbon \u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFork - \u003c\/strong\u003eFACT 12r Carbon with Aerodynamic Optimization\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTire Clearance - \u003c\/strong\u003eUp to 55mm \/ 2.2\" with Zero Compromises\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Specialized Bikes","offers":[{"title":"Cayenne Metallic \/ 49","offer_id":48222606622965,"sku":"71427-0249","price":5799.99,"currency_code":"USD","in_stock":true},{"title":"Cayenne Metallic \/ 52","offer_id":48222606655733,"sku":"71427-0252","price":5799.99,"currency_code":"USD","in_stock":false},{"title":"Cayenne Metallic \/ 54","offer_id":48222606688501,"sku":"71427-0254","price":5799.99,"currency_code":"USD","in_stock":true},{"title":"Cayenne Metallic \/ 56","offer_id":48222606721269,"sku":"71427-0256","price":5799.99,"currency_code":"USD","in_stock":false},{"title":"Cayenne Metallic \/ 58","offer_id":48222606754037,"sku":"71427-0258","price":5799.99,"currency_code":"USD","in_stock":false},{"title":"Cayenne Metallic \/ 61","offer_id":48222606786805,"sku":"71427-0261","price":5799.99,"currency_code":"USD","in_stock":false},{"title":"Agave Grey \/ 49","offer_id":48222606819573,"sku":"71427-0149","price":5799.99,"currency_code":"USD","in_stock":false},{"title":"Agave Grey \/ 52","offer_id":48222606852341,"sku":"71427-0152","price":5799.99,"currency_code":"USD","in_stock":false},{"title":"Agave Grey \/ 54","offer_id":48222606885109,"sku":"71427-0154","price":5799.99,"currency_code":"USD","in_stock":false},{"title":"Agave Grey \/ 56","offer_id":48222606917877,"sku":"71427-0156","price":5799.99,"currency_code":"USD","in_stock":false},{"title":"Agave Grey \/ 58","offer_id":48222606950645,"sku":"71427-0158","price":5799.99,"currency_code":"USD","in_stock":false},{"title":"Agave Grey \/ 61","offer_id":48222606983413,"sku":"71427-0161","price":5799.99,"currency_code":"USD","in_stock":false},{"title":"Satin Carbon \/ 49","offer_id":48222608752885,"sku":"71427-0349","price":5799.99,"currency_code":"USD","in_stock":false},{"title":"Satin Carbon \/ 52","offer_id":48222608785653,"sku":"71427-0352","price":5799.99,"currency_code":"USD","in_stock":false},{"title":"Satin Carbon \/ 54","offer_id":48222608818421,"sku":"71427-0354","price":5799.99,"currency_code":"USD","in_stock":false},{"title":"Satin Carbon \/ 56","offer_id":48222608851189,"sku":"71427-0356","price":5799.99,"currency_code":"USD","in_stock":false},{"title":"Satin Carbon \/ 58","offer_id":48222608883957,"sku":"71427-0358","price":5799.99,"currency_code":"USD","in_stock":false},{"title":"Satin Carbon \/ 61","offer_id":48222608916725,"sku":"71427-0361","price":5799.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0483\/9040\/6312\/files\/Specialized_S-Works_Crux_5_Frameset_Satin_Carbon_Contender_Bicycles.jpg?v=1780447518","url":"https:\/\/contenderbicycles.com\/products\/specialized-s-works-crux-5-frameset","provider":"Contender Bicycles","version":"1.0","type":"link"}
