Wheelset 404 NSW TL DBCL 7r XDR 12x142 Std A2

ZIPP 404 NSW Carbon (Rear)
The Zipp 404 NSW Tubeless Disc-brake wheel offers a new rim shape with greater aerodynamic efficiency and reduced side force as well as the Cognition disc-brake hubs for increased durability and less drag. The 404 NSW Tubeless Disc-brake, with a rim depth of 58mm, is designed for road cyclists and triathletes looking for increased speed and stability. The 404 NSW Tubeless features a rim shape that aerodynamically integrates wider tubeless tires for enhanced ride quality and performance. The benefits of tubeless include superior flat protection, the ability to run lower pressures, and a smoother ride with high cornering grip and low rolling resistance. This wheelset, though, allows you to run tubeless or traditional clinchers.

 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.

Cognition Hub

With the Cognition hubset’s Axial Clutch technology, Zipp has 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.
