ZIPP 858 NSW Carbon Wheelset - Tubeless - Centerlock - FW: 12x100mm | RW: 12x142mm - black

 

Zipp’s ultimate aero weapon is fast in the wind and on the ground.

That means you get the many aero advantages of the 858 NSW Tubeless disc-brake wheelset with the added benefit of increased cornering grip and compliance with reduced rolling resistance. The wheelset’s 18mm internal width is optimized for running wider tires at reduced air pressure. The 858 NSW’s undulating 77/82mm-deep rim shape, with a proprietary Sawtooth™ profile, takes design cues from nature for the highest performing wheel when it comes to aero efficiency and crosswind stability. These structures inspired Zipp advanced development engineers to, for the first time, systematically apply biomimicry to solve the complex challenge of designing a wheel, with the undulating Hyperfoil™ nodes, that reduces both aerodynamic drag and side force. Simply put, the 858 NSW Tubeless is ideal for those focused on triathlon, time trials, or aggressive road riding.

 


ABLC Sawtooth
Zipp’s Sawtooth dimple design consists of 12 nodes that are specifically clocked to start aerodynamic shearing at a rate of 50hz at a rider speed of 20mph. Sawtooth accomplishes this by inducing small sheet vortices that shed at a low magnitude, but at a higher natural frequency, thus decreasing the laminar bubble effect on the aerodynamically shielded side of the rim’s profile to further reduce high yaw drag and improve crosswind stability.


Showstopper
The industry leading silicon carbide Showstopper brake track continues to evolve and improve, providing unmatched stopping power and modulation regardless of weather conditions or the length of the descent.

 

Cognition V2 Hub

With the Cognition V2 hubset’s Axial Clutch V2 technology, Zipp have reduced this drag by disengaging the ratchet mechanism when coasting. So you can approach corners at higher speeds, and ultimately, save time. A star-flanged straight-pull hubshell design on the rear hub distributes the load placed on the hub flange away from the bearings. They’ve also developed a unique scalloped edge hubshell design for the front hub. This scalloped design maintains the bearing bore diameter when high radial spoke tension is applied. That means you get bearings that quietly stay in place, roll faster, last longer, and provide a laterally stiffer hub.
