To go faster than ever before, the wheels, trimmed for maximum aerodynamic efficiency, rely on the Total System Efficiency (TSE) concept, which combats the four biggest obstacles of high speeds: air resistance, gravity, rolling resistance and vibratory losses.\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003eThe 858 NSW wheels offer the aerodynamic benefits of tall rims at a weight normally achieved with a 20 mm lower profile height. This is made possible by ZIPP's Carbon Internal Reinforcement (CiR) technology, which achieves a weight reduction of 10 percent, or 280 grams, over the previous model without compromising rim stability. The undulating rim shape with slightly iridescent profile height, in concert with the sophisticated ABLC Sawtooth™ Dimple Design, which on the 858 NSW features different sized Hyperfoil dimples in a HexFin arrangement, results in ZIPP's highest-performing design in terms of aeroefficiency and crosswind stability.\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003eWhile the combination of Tubeless technology with Hookless rim flanks provides a seamless transition between tire and rim, the combination of Tubeless concept and 23 mm inner width allows riding wider tires and with lower pressure – for less rolling resistance and better cornering grip. Especially in triathlon, this smoother ride makes itself felt positively by sparing the legs for the subsequent run. The highest speeds achieve the ZIPP 858 NSW Disc wheels with 28 mm wide tires. Despite the Tubeless optimization, it is possible to use Tubeless tires in combination with a tube.\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003eAt the heart of the 858 NSW wheels are the Cognition V2 hubs, which are not only characterized by reliability and long durability, but thanks to Axial Clutch technology also reduce resistance and friction for an even more spontaneous response. Thanks to their orientation to disc brakes, reliable speed control and adequate braking power is guaranteed in all weather conditions.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cp\u003eHighlights:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eZipp’s most advanced and fastest deep-rim wheel for road, triathlon, and time trialling\u003c\/li\u003e\n\u003cli\u003eMore than 300 grams lighter that previous model\u003c\/li\u003e\n\u003cli\u003eOptimized tire bed for easy tyre installation\u003c\/li\u003e\n\u003cli\u003eTSE for greater efficiency and reduced rolling resistance\u003c\/li\u003e\n\u003cli\u003eSawtooth rim with Hyperfoil nodes and HexFin ABLC dimple pattern for top aero and crosswind-stability performance with an undulating rim depth\u003c\/li\u003e\n\u003cli\u003eConceived via Zipp’s “Total System Efficiency” (TSE) design concept that equally factors aerodynamics, weight, rolling resistance and vibration losses (comfort)\u003c\/li\u003e\n\u003cli\u003eA special tool that measures aerodynamic drag, rolling resistance, wind speed and wind yaw angle while on the road, was key in the development of these wheels \u003c\/li\u003e\n\u003cli\u003eThe TSE holistic design approach equals more speed in real-world riding conditions rather than just wind tunnels\u003c\/li\u003e\n\u003cli\u003eThe rims use the highest grade of carbon fibre to lower weight, increase strength and improve lateral stiffness\u003c\/li\u003e\n\u003cli\u003eThe hookless internal rim design is for tubeless-ready tyres only, promotes a more aerodynamic tyre to rim interface and lowers weight via more even resin distribution\u003c\/li\u003e\n\u003cli\u003eA 23mm internal rim width works optimally with wider tubeless-ready tyres, lowering rolling resistance and improving comfort\u003c\/li\u003e\n\u003cli\u003eThe SawTooth rim profile increases lateral stiffness for faster climbing and snappier acceleration\u003c\/li\u003e\n\u003cli\u003eHexFin ABLC rim surface dimple pattern further lowers drag\u003c\/li\u003e\n\u003cli\u003eZipp graphics applied using Zipp’s ImPress direct-print technology\u003c\/li\u003e\n\u003cli\u003eCognition V2 hubset with an Axial Clutch V2 freehub for decreased resistance when freewheeling and almost instant pedalling engagement\u003c\/li\u003e\n\u003cli\u003eSapim CX-Ray spokes\u003c\/li\u003e\n\u003cli\u003eLifetime Warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e: \u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eTyre compatibility: Tubeless-ready only\u003c\/li\u003e\n\u003cli\u003eWheel Size: 700c\u003c\/li\u003e\n\u003cli\u003eRim: Full carbon with a SawTooth profile and HexFin ABLC rim surface dimples\u003c\/li\u003e\n\u003cli\u003eRim profile: Symmetrical\u003c\/li\u003e\n\u003cli\u003eRim finish: UD fibre, Impress technology\u003c\/li\u003e\n\u003cli\u003eRim depth: 82\/85mm, undulating\u003c\/li\u003e\n\u003cli\u003eInternal rim width: 23mm\u003c\/li\u003e\n\u003cli\u003eRim internal format: Hookless (straight sides)\u003c\/li\u003e\n\u003cli\u003eSpokes: Sapim CX-Ray\u003c\/li\u003e\n\u003cli\u003eSpoke lacing pattern: Front: Two-cross \/ Rear: Two-cross\u003c\/li\u003e\n\u003cli\u003eSpoke count: Front: 24 \/ Rear: 24\u003c\/li\u003e\n\u003cli\u003eHubs: Front: Zipp Cognition V2 \/ Rear: Zipp Cognition V2 with Axial Clutch technology\u003c\/li\u003e\n\u003cli\u003eBearings: Cartridge - stainless steel\u003c\/li\u003e\n\u003cli\u003eFreehub compatibility: SRAM XDR or Shimano HG\/SRAM Road 11-speed\u003c\/li\u003e\n\u003cli\u003eBrake compatibility: Disc\u003c\/li\u003e\n\u003cli\u003eDisc standard: Center Lock\u003c\/li\u003e\n\u003cli\u003eAxle: 12mm x 142mm thru-axle compatible\u003c\/li\u003e\n\u003cli\u003eManufacturer claimed weight: 811g\u003c\/li\u003e\n\u003cli\u003eWarranty: Lifetime\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Zipp","offers":[{"title":"Rear (Shimano HG)","offer_id":56631445651843,"sku":"WH80810 \/ UL6","price":1369.0,"currency_code":"USD","in_stock":true},{"title":"Rear (XDR)","offer_id":56631445684611,"sku":"WH79906 \/ UL6","price":1369.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0582\/0196\/4698\/files\/Zipp-858-NSW-Carbon-Rear-Wheel-2025-Black.webp?v=1760440005","url":"https:\/\/sportandleisure.com\/en-us\/products\/zipp-858-nsw-carbon-tubeless-road-bike-rear-wheel","provider":"Sport \u0026 Leisure","version":"1.0","type":"link"}
