Zipp 454 NSW Carbon Tubeless Disc Brake Rear Wheel - Sram XDR

The Zipp 454 NSW Carbon Tubeless Disc Brake Rear Wheel is built for maximum speed, stability, and efficiency in real-world racing conditions. Its 58mm Sawtooth rim with Hyperfoils delivers unmatched aerodynamic performance and crosswind stability. The hookless carbon rim supports lower tyre pressures, improving rolling resistance and ride comfort. Lightweight construction, ceramic bearings, and rapid engagement combine to reduce energy loss and increase control making this wheel a serious upgrade for performance riders.Key Features and Benefits:58mm Sawtooth carbon rim with Hyperfoils: Reduces aerodynamic drag while enhancing stability in changing wind conditions. This allows you to maintain speed more easily without fighting the bike in crosswinds.Total System Efficiency (TSE) design: Combats drag, gravity, vibration, and rolling resistance together. Helps transfer more of your effort into forward motion, resulting in sustained high speed with less fatigue.Hookless rim construction: Creates a smoother tyre-to-rim profile, which improves aerodynamics and tyre support. This setup increases airflow efficiency and boosts cornering confidence.Wider 23mm internal rim width: Designed for 28mm tubeless tyres, allowing lower pressures. This reduces rolling resistance and increases comfort by absorbing road vibrations, leading to more efficient power output.ZR1 SL rear hub with ceramic bearings: Offers smooth rotation and 66 points of engagement for quicker power transfer. This ensures immediate response when accelerating or climbing.Lighter resin distribution in carbon layup: Achieves a lower overall wheel weight without sacrificing strength. Riders benefit from faster acceleration and easier climbing.Disc-brake specific design with centre lock compatibility: Enhances braking performance in all weather conditions. This provides greater control and confidence on descents or during sudden stops.Sapim CX-Ray spokes and Secure-Loc nipples: Improves wheel durability and maintains tension under load. This ensures long-term performance and consistent handling under racing stress.The main advantage this wheel offers is greater sustained speed with less effort across real-world conditions. The aerodynamic rim profile, rolling resistance reduction, and instant drivetrain response are all engineered to deliver maximum performance gains without compromise. By combining cutting-edge carbon shaping with practical efficiency upgrades, the 454 NSW delivers the exact qualities that serious road cyclists need: fast, stable, and efficient riding over long distances and varied terrain.Push your performance further with a rear wheel designed to keep you moving faster, longer, and with greater control. Take advantage of proven aerodynamics, responsive power transfer, and advanced tubeless compatibility in one focused package.Specification:Orientation (wheels): RearSize (wheels): 700cRim construction: Carbon HooklessTyre compatibility: Tubeless tyres onlyRim depth: 58mmSurface texture: ABLC SawToothBrake compatibility: Disc (Centre Lock)Rim - inside width: 23mmRim profile: SymmetricalRim finish: UD fibre, Impress technologyNipple material: AluminiumNipple anti-rotation: Sapim Secure-LocSpoke type: CX-Ray - BlackSpoke count: 24Spoke pattern: 2 CrossHub: ZR1 SLDriver body type: SRAM/Shimano RoadColour (Decal): StandardColour (hub): BlackAxle type (wheels): TA 12x142Axle material: Aluminium front & rearBearings: Cartridge - CeramicDriver mechanism: 6 Pawls Compression, 66 POEDriver body material: AluminiumMax tyre pressure: 73psi / 5.0barMax recommended system weight: 250lbs / 114kgSpoke length DS: 252mmSpoke length NDS: 256mmMax outside width: 28mm
