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 Carbon Clincher Disc 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 Disc brake’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; while it’s disc-specific rim design features our patented NSW-exclusive HexFin ABLC dimples extending all the way to the rim’s edge for maximum aero efficiency and crosswind stability.
Designed for road or triathlon applications, the 858 Carbon Clincher NSW Disc brake’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.

Axial Clutch™ technology
With Cognition’s Axial Clutch™ technology, we’ve reduced this drag by disengaging the ratchet mechanism when coasting. With less internal hub drag a rider can pedal less when drafting in a headwind, achieve higher speeds when coasting in an aero tuck, or opt to stop pedaling a moment sooner before entering a corner and bank that wattage for use exiting the corner. Axial Clutch technology also allows riders to maintain speed through corners that don’t require braking input, thereby increasing corner exit speeds. Inside the Axial Clutch mechanism we use magnets, rather than steel springs, to move and engage our light weight Metal Injection Molded (MIM) ratchet rings for unmatched reliability and consistent operation. With 36 points of engagement that all interlock simultaneously, there isn’t a more secure freehub mechanism on the market.
SawTooth™ is the name given to Zipp NSW’s patented variable depth 53/58mm rims. Developed utilizing the principles of the emerging science of biomimicry, Zipp engineers began the rigorous aero development process of SawTooth™ utilizing the wind tunnel, CFD, and real-world testing. The result is a rim shape that takes nature’s most elegant design solutions and combines engineering precision to deliver a wheel that performs unlike any made before.
This patented new rim shape achieves something conventional aero wheels cannot; it simultaneously reduces both aerodynamic drag and side force for the ultimate in AeroBalance™. Sawtooth™ accomplishes this with a series of patented fin-shaped Hyperfoil™ nodes along the inner diameter of the rim that work together with our new HexFin™ ABLC dimples for improved airflow. The result is Zipp’s highest performing wheelset ever realized with both aero-drag reduction and reduced side force at all wind yaw angles. This is important because higher wind yaw angles are where bike handling is most affected by the wind.
Hyperfoil™ is the name given to the individual nodes on Zipp NSW variable depth Sawtooth™ rims. Each of these patented structures features our HexFin™ ABLC dimples that help to stabilize handling in gusting wind by increasing wind vortex shedding frequency. 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.
HexFin™ ABLC dimples
HexFin™ ABLC dimples are the hexagonally shaped depressions found at each Hyperfoil™ of our Sawtooth™ shaped NSW rims. The angular shape of each dimple increases boundary layer mixing to help keep airflow attached to the rim for reduced aerodynamic drag and improved stability in crosswinds. To further improve the effectiveness of the hexagonal dimples, they are arranged in fin-shaped clusters made up of variable sized dimples that work in concert with each Hyperfoil™ of a Sawtooth™ rim.
