Zipp 858 NSW Carbon Clincher Wheelset: With the introduction of the radical biomimicry-derived 454 NSW Carbon Clincher, Zipp proved that aero efficiency and crosswind stability are not mutually exclusive aero wheel design goals. Using a similar Sawtooth™ rim design, the 858 NSW rim brake wheelset goes 24 millimeters deeper than the 454 and delivers even greater gains in aero efficiency while providing a level of rider control in crosswinds that was previously unthinkable with conventional deep-section wheel designs. By minimizing concerns over control, the 858 NSW ushers in a new era where aerodynamically efficient deep-section wheels are no longer reserved only for ideal racing conditions—the 858 NSW is an every-condition race wheelset.
Adding to the 858 NSW’s versatility, its lightweight and laterally stiff rim imparts a level of responsiveness previously only attributed to much shallower wheels, keeping bike handling lively and quick. The 858 NSW also delivers the best braking available thanks to our NSW-exclusive Showstopper® brake track.
Designed for road or triathlon applications, the 858 NSW’s advanced aero efficiency, crosswind stability, responsive handling, and unrivalled braking are engineered to make what was once impossible… possible.
Faster than an 808. Rides Like a 404.
The 454 NSW’s undulating Sawtooth rim architecture with HyperFoils represents the next evolution of the Sawtooth ABLC dimple technology found on all of Zipp's NSW wheels. The HyperFoils and HexFin ABLC dimples help to stabilize handling in gusting wind by increasing wind vortex shedding frequency. Lower frequency shedding produces larger, more powerful vortices. In cycling terms, this unstable situation is often referred to as “buffeting.” The higher frequency vortex shedding produced by Sawtooth™ creates a greater number of smaller, less powerful, yet more predictable vortices leading to greater wheel stability.
This added stability translates into greater rider control, thereby saving energy that is typically expended trying to hold a line in gusting wind. The result is a faster, more confident riding experience whether you are laying down power or descending sinuous mountain roads. Providing extra confidence, Zipp’s industry leading Carbon Clincher technology is durable and reliable, with no heat-related failures.
The 454 NSW also features our industry leading silicon carbide Showstopper brake track that allows you to brake later with more stopping power and greater control regardless of weather conditions or the length of the descent. Zipp's ImPress NSW graphics technology, which prints graphics directly onto the rim, reduces weight and helps the HexFin ABLC dimples to do their aerodynamic job while elevating the wheel’s visual allure to new heights.
BEYOND THE RIM SHAPE
Making use of our NSW-exclusive Cognition hubset, 454 NSW rolls efficiently whether you are pedaling or coasting. Our Axial Clutch technology allows the freehub's ratcheting mechanism to deliver half the mechanical drag of conventional three pawl hubs. Assembled with Swiss bearings made to our exacting specifications, the Cognition hubset is as robust as it is fast.
Each Indianapolis-made 454 NSW rim requires 12 hours to create and represents a true blending of hand craftsmanship and advanced manufacturing techniques. After each rim is laid up, molded, drilled, printed, and inspected, every wheel is assembled and tensioned entirely by hand in Indianapolis. 454 NSW rims are laced to our Portuguese-made Cognition hubs using Belgian Sapim CX-Ray spokes and Secure Lock nipples for unmatched performance and reliability that is made to last.
