{"product_id":"zipp-404-s-carbon-wheelset","title":"404 S Carbon Wheelset","description":"\u003cp\u003eThe Zipp 404 S wheelset is built to be the fastest road wheelset Zipp make at this price — flagship-derived aerodynamics without the flagship cost. Stepping on from the 303 S, it takes its 50mm mid-depth rim profile from Zipp's WorldTour-proven Firecrest design, delivering premium aero performance while staying shallow enough to keep the bike composed in crosswinds.\u003c\/p\u003e\n\u003cp\u003eZipp claim the 404 S saves around two watts over the 303 S, with similar gains over rival wheels costing well over twice as much. Both rims are hookless, tubeless-only Tubeless Straight Side designs, so with modern tubeless tyres they run lower pressures for a smoother, faster, grippier ride. At a claimed 1545g the pair (707g front, 838g rear) it's light enough for all-day road riding as well as fast-day efforts.\u003c\/p\u003e\n\u003cp\u003eThe wheels spin on Zipp's 76 and 176 hubs with 36 points of engagement for quick, reliable pick-up, laced with durable Sapim CX-Sprint spokes in a 2-cross build. Supplied as a front and rear pair with a choice of SRAM\/Shimano HG or SRAM XDR freehub, in Dark Grey or White.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e50mm Firecrest-derived rim profile for premium aerodynamics with crosswind stability\u003c\/li\u003e\n\u003cli\u003eAround 2 watts faster than the 303 S\u003c\/li\u003e\n\u003cli\u003eClaimed 1545g the pair (707g front, 838g rear)\u003c\/li\u003e\n\u003cli\u003eHookless, tubeless-only Tubeless Straight Side (TSS) rims\u003c\/li\u003e\n\u003cli\u003eZipp 76 \/ 176 hubs with 36 points of engagement\u003c\/li\u003e\n\u003cli\u003eSapim CX-Sprint spokes, 20-hole 2-cross\u003c\/li\u003e\n\u003cli\u003e700c, disc brake (Center Lock); 12 × 100mm front, 12 × 142mm rear\u003c\/li\u003e\n\u003cli\u003eChoice of SRAM\/Shimano HG or SRAM XDR freehub; Dark Grey or White\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecification\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eWheels: Front and rear pair\u003c\/li\u003e\n\u003cli\u003eWeight: 1545g the pair (707g front, 838g rear)\u003c\/li\u003e\n\u003cli\u003eRim depth: 50mm\u003c\/li\u003e\n\u003cli\u003eRim construction: Carbon, hookless Tubeless Straight Side (TSS)\u003c\/li\u003e\n\u003cli\u003eTyre compatibility: Tubeless tyres only\u003c\/li\u003e\n\u003cli\u003eBrake: Disc, Center Lock\u003c\/li\u003e\n\u003cli\u003eAxles: 12 × 100mm front, 12 × 142mm rear\u003c\/li\u003e\n\u003cli\u003eFreehub: SRAM\/Shimano HG or SRAM XDR\u003c\/li\u003e\n\u003cli\u003eHubs: Zipp 76 \/ 176, 36 points of engagement\u003c\/li\u003e\n\u003cli\u003eBearings: Stainless steel cartridge\u003c\/li\u003e\n\u003cli\u003eSpokes: Sapim CX-Sprint, 20-hole 2-cross\u003c\/li\u003e\n\u003cli\u003eMax tyre pressure: 73psi \/ 5.0 bar\u003c\/li\u003e\n\u003cli\u003eMax system weight: 115kg \/ 253lbs\u003c\/li\u003e\n\u003cli\u003eColours: Dark Grey, White\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Zipp","offers":[{"title":"Dark Grey \/ 12 x 142mm HG","offer_id":58184657633654,"sku":"ZPWS404SSG","price":985.0,"currency_code":"GBP","in_stock":false},{"title":"White \/ 12 x 142mm HG","offer_id":58184657666422,"sku":"ZPWS404SSW","price":985.0,"currency_code":"GBP","in_stock":false},{"title":"Dark Grey \/ 12 x 142mm XDR","offer_id":58184657699190,"sku":"ZPWS404SXG","price":985.0,"currency_code":"GBP","in_stock":false},{"title":"White \/ 12 x 142mm XDR","offer_id":58184657731958,"sku":"ZPWS404SXW","price":985.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0568\/3065\/6691\/files\/404-s-carbon-wheelset-dark-grey-12-x-142mm-hg-1246720743.png?v=1782895424","url":"https:\/\/www.biketart.com\/products\/zipp-404-s-carbon-wheelset","provider":"Biketart","version":"1.0","type":"link"}
