Expanding on its heritage of conquering the Spring Classics, this wheelset maintains an ideal-for-every-terrain 45mm rim depth while introducing a significantly wider internal width to provide greater performance and ride quality in almost every measurable way. Road bikes are more versatile than ever, and the 303 S offers an entirely new rim profile and design to optimize rider performance on this new breed of bike, no matter the road surface.\u003c\/p\u003e \n\u003cp\u003eThis wheelset is purpose-built for tubeless disc-brake bikes, allowing riders to run wide tires at lower pressures for race-ready speed on or off the pavement. As one of our lightest wheelsets, the 303 S is optimized for top aero performance with a 28mm tire but remains capable of handling gravel tires up to 50mm wide. By borrowing design concepts from the higher-level Firecrest series, it gains speed through increased efficiency, reducing wind resistance, rolling resistance, rider fatigue, and weight.\u003c\/p\u003e\n\u003cp\u003eThe key innovation lies in the hookless rim design. The 23mm internal tire bed is designed to be fastest with a 28mm tire, optimizing the tire profile to allow lower pressures. This reduces rolling resistance and provides a more compliant ride. Internal testing shows a 10 percent watt savings versus a top peer wheel in total power required to ride 40kph on a smooth flat road. These wheels also feature striking graphics that set you apart from the pack while delivering groundbreaking technology at an attractive price.\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"text-decoration: underline;\"\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eNew Zipp graphics and cosmetic identity that scream speed\u003c\/li\u003e\n  \u003cli\u003eFastest with 28mm, fits wide gravel tires as well\u003c\/li\u003e\n  \u003cli\u003e76 \/ 176 DB hubs with Center locking interface\u003c\/li\u003e\n  \u003cli\u003eSRAM XDR and Shimano\/SRAM driver body options\u003c\/li\u003e\n  \u003cli\u003eWide rims optimize tire profile for a larger contact patch, increasing grip for confident cornering and handling in wet conditions\u003c\/li\u003e\n  \u003cli\u003eLower tire pressures and larger volume provides a compliant ride with fewer vibrations\u003c\/li\u003e\n  \u003cli\u003eSignificant watt savings when running larger tires at lower pressure\u003c\/li\u003e\n  \u003cli\u003eWide hookless rims create a seamless transition to the tire, reducing drag\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan style=\"text-decoration: underline;\"\u003e\u003cstrong\u003eSPECIFICATIONS\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHookless rims:\u003c\/strong\u003e Yes\u003cbr\u003e\n\u003cstrong\u003eSize (wheels):\u003c\/strong\u003e 700c\u003cbr\u003e\n\u003cstrong\u003eRim construction:\u003c\/strong\u003e Carbon\u003cbr\u003e\n\u003cstrong\u003eTire compatibility:\u003c\/strong\u003e Clincher Tubeless Ready\u003cbr\u003e\n\u003cstrong\u003eRim depth:\u003c\/strong\u003e 45mm\u003cbr\u003e\n\u003cstrong\u003eSurface texture:\u003c\/strong\u003e Smooth\u003cbr\u003e\n\u003cstrong\u003eBrake compatibility:\u003c\/strong\u003e Disc (Center Lock)\u003cbr\u003e\n\u003cstrong\u003eRim - inside width:\u003c\/strong\u003e 23mm\u003cbr\u003e\n\u003cstrong\u003eRim profile:\u003c\/strong\u003e Symmetrical\u003cbr\u003e\n\u003cstrong\u003eRim finish:\u003c\/strong\u003e UD fiber \/ Bake-On labels \/ Matte clear coat\u003cbr\u003e\n\u003cstrong\u003eNipple material:\u003c\/strong\u003e Brass\u003cbr\u003e\n\u003cstrong\u003eNipple anti-rotation:\u003c\/strong\u003e Sapim Secure-Loc\u003cbr\u003e\n\u003cstrong\u003eSpoke type:\u003c\/strong\u003e CX-Sprint\u003cbr\u003e\n\u003cstrong\u003eSpoke count:\u003c\/strong\u003e 24\u003cbr\u003e\n\u003cstrong\u003eSpoke pattern:\u003c\/strong\u003e 2 Cross\u003cbr\u003e\n\u003cstrong\u003eBearings:\u003c\/strong\u003e Cartridge - Stainless Steel\u003cbr\u003e\n\u003cstrong\u003eMax tire pressure:\u003c\/strong\u003e 73psi\u003cbr\u003e\n\u003cstrong\u003eMax recommended rider weight:\u003c\/strong\u003e 250lbs\u003c\/p\u003e","brand":"Zipp","offers":[{"title":"Front wheel","offer_id":57147271020888,"sku":"ZPWH8527000","price":519.0,"currency_code":"GBP","in_stock":true},{"title":"SRAM 10\/11sp","offer_id":57147271053656,"sku":"ZPWH8528000","price":569.0,"currency_code":"GBP","in_stock":true},{"title":"XDR","offer_id":57147271086424,"sku":"ZPWH8528001","price":569.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/5247\/5224\/files\/ZPWH8527000_45797.jpg?v=1776689792","url":"https:\/\/www.leadoutperformance.co.uk\/products\/zipp-303-s-carbon-tubeless-disc-brake-center-locking-700c","provider":"Leadout Performance","version":"1.0","type":"link"}
