ZIPP 303 XPLR SW Tubeless Disc Wheelset The Zipp 303 XPLR SW is engineered for riders chasing ultimate gravel performancebuilt around a mega-wide, aero-optimised rim designed to integrate perfectly with high-volume gravel tyres.* Unlike nominal road-derived gravel wheels, the 303 XPLR SW emphasises Total System Efficiency (TSE) for gravel: wider tyre volume and lower pressures deliver better vibration damping, improved traction, and reduced rolling resistance on rough surfaces. Its seamless tyre-to-rim interface enhances aerodynamics in real-world conditions where typical gravel tyres and rims don’t play well together. Despite its purposeful size, the 303 XPLR SW remains lightweight to keep you fast and fresh through long days of racing or adventure riding. This wheelset is compatible only with approved tyres , ensuring safety and performance integrity. Recommended Tyre Compatibility For optimal performance and safe hookless sealing, Zipp’s 303 XPLR SW is designed around specific gravel tyres developed in partnership with Goodyear: Tyres Optimised for 303 XPLR SW Goodyear XPLR Slick Tyre - Ultra-fast gravel racing tyre with a mostly slick centre, designed for smooth to mixed surfaces and maximised aero efficiency on the wide 303 XPLR rims. Goodyear XPLR Inter Tyre - Versatile gravel tyre with intermediate tread and larger volume, suited to varied terrain and conditions from hardpack to rougher gravel. Both XPLR Slick and XPLR Inter tyres are engineered specifically for this rim’s 32 mm internal width , yielding proper bead seating, predictable handling, and the intended tyre profile at lower pressures. Note: Zipp only supports tyres listed on its official compatibility chart for this model; other tyres may not seal or perform correctly with the unique 303 XPLR SW hookless interface and wide rim bed. Whilst Zipp recommend Goodyear XPLR tyres, they are not the only tyres approved by Zipp. A FULL LIST OF APPROVED TYRES CAN BE FOUND HERE APPROVED TYRES Key Benefits Gravel-specific design focused on speed, comfort, and control Ultra-wide hookless carbon rim with excellent tyre support at low pressures Seamless tyre-rim interface for enhanced aero performance on gravel Lightweight build to support long-distance efficiency and responsiveness Lifetime warranty for structural integrity Specifications Wheel size: 700c Rim construction: Carbon - Hookless Tyre compatibility: Tubeless tyres only (approved tyres list) Rim depth: 54 mm Internal width: 32 mm Brake compatibility: Disc, Center Lock Rim profile: Symmetrical Spokes: 24 CX-Ray, 2-cross, aluminium nipples Bearings: Cartridge, carbon steel Freehub options: SRAM XDR, SRAM/Shimano Road Axle standard: 12100 mm thru-axle Max tyre pressure: 50 psi / 3.45 bar Max recommended system weight: 130 kg / 286 lbs Weight: ~1452 g (lightest configuration; incl. tape + valve)
