{"product_id":"zipp-303-xplr-s-carbon-gravel-wheelset-b1","title":"303 XPLR S Carbon Gravel Wheelset B1","description":"\u003cp\u003eThe Zipp 303 XPLR S is a big upgrade for gravel riders without the big price tag — a mega-wide, fast-rolling wheelset that borrows key innovations from Zipp's premium wide gravel wheels and makes them far more affordable. It's built around Total System Efficiency, applied specifically to the challenges of riding fast off-road.\u003c\/p\u003e\n\u003cp\u003eOn gravel, vibration and rolling resistance from rough surfaces are what really slow you down. The 303 XPLR S tackles this with an ultra-wide 32mm internal rim that increases tyre air volume, letting you run pressures under 30psi without squirm. The result is less vibration, more grip through corners and better traction when climbing, while the wide, 54mm-deep profile blends smoothly into approved gravel tyres for genuine aero efficiency. Built big but kept light, it's made for long, fulfilling days in the saddle.\u003c\/p\u003e\n\u003cp\u003eBoth rims are hookless, tubeless carbon, laced to Zipp's 76 and 176 hubs with 36 points of engagement, supplied as a front and rear pair with a choice of SRAM\/Shimano HG or SRAM XDR freehub. Please note the 303 XPLR is compatible only with Zipp-approved tyres. Available in Dark Grey or White, and backed by Zipp's lifetime warranty.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMega-wide 32mm internal rims — run gravel tyres below 30psi without squirm\u003c\/li\u003e\n\u003cli\u003e54mm deep, wide profile integrates with approved tyres for aero efficiency on gravel\u003c\/li\u003e\n\u003cli\u003eHookless carbon, tubeless rims — built big yet light for long days\u003c\/li\u003e\n\u003cli\u003eZipp 76 \/ 176 hubs with 36 points of engagement\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\u003c\/li\u003e\n\u003cli\u003eCompatible with Zipp-approved tyres only (40–61c); lifetime warranty; 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\u003eDiscipline: Gravel\u003c\/li\u003e\n\u003cli\u003eWeight: approx. 1610g (pair)\u003c\/li\u003e\n\u003cli\u003eRim depth: 54mm\u003c\/li\u003e\n\u003cli\u003eRim construction: Carbon, hookless\u003c\/li\u003e\n\u003cli\u003eInternal rim width: 32mm\u003c\/li\u003e\n\u003cli\u003eMax outside width: 40mm\u003c\/li\u003e\n\u003cli\u003eTyre compatibility: Approved tubeless (TLR) tyres 40–61c, tube or sealant\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\u003eMax tyre pressure: 50psi \/ 3.45 bar\u003c\/li\u003e\n\u003cli\u003eMax system weight: 135kg \/ 298lbs\u003c\/li\u003e\n\u003cli\u003eWarranty: Lifetime\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":58184657994102,"sku":"ZPWS303XPLRSSG","price":1100.0,"currency_code":"GBP","in_stock":true},{"title":"White \/ 12 x 142mm HG","offer_id":58184658026870,"sku":"ZPWS303XPLRSSW","price":1100.0,"currency_code":"GBP","in_stock":true},{"title":"Dark Grey \/ 12 x 142mm XDR","offer_id":58184658059638,"sku":"ZPWS303XPLRSXG","price":1100.0,"currency_code":"GBP","in_stock":true},{"title":"White \/ 12 x 142mm XDR","offer_id":58184658092406,"sku":"ZPWS303XPLRSXW","price":1100.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0568\/3065\/6691\/files\/303-xplr-s-carbon-gravel-wheelset-b1-dark-grey-12-x-142mm-hg-1246720736.jpg?v=1782895303","url":"https:\/\/www.biketart.com\/products\/zipp-303-xplr-s-carbon-gravel-wheelset-b1","provider":"Biketart","version":"1.0","type":"link"}
