Description
Zipp 858 NSW Carbon Tubeless Road Bike Rear Wheel

Pure speed for triathlon, time trial and aggressive road cycling is the objective of the 858 NSW wheelset. 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.

The 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.

While 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.

At 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.

Highlights:

  • Zipp’s most advanced and fastest deep-rim wheel for road, triathlon, and time trialling
  • More than 300 grams lighter that previous model
  • Optimized tire bed for easy tyre installation
  • TSE for greater efficiency and reduced rolling resistance
  • Sawtooth rim with Hyperfoil nodes and HexFin ABLC dimple pattern for top aero and crosswind-stability performance with an undulating rim depth
  • Conceived via Zipp’s “Total System Efficiency” (TSE) design concept that equally factors aerodynamics, weight, rolling resistance and vibration losses (comfort)
  • A 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 
  • The TSE holistic design approach equals more speed in real-world riding conditions rather than just wind tunnels
  • The rims use the highest grade of carbon fibre to lower weight, increase strength and improve lateral stiffness
  • The 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
  • A 23mm internal rim width works optimally with wider tubeless-ready tyres, lowering rolling resistance and improving comfort
  • The SawTooth rim profile increases lateral stiffness for faster climbing and snappier acceleration
  • HexFin ABLC rim surface dimple pattern further lowers drag
  • Zipp graphics applied using Zipp’s ImPress direct-print technology
  • Cognition V2 hubset with an Axial Clutch V2 freehub for decreased resistance when freewheeling and almost instant pedalling engagement
  • Sapim CX-Ray spokes
  • Lifetime Warranty
