- OVERVIEW
- TECHNICAL SPECIFICATIONS
The 454 NSW features Zipp’s most advanced technologies. Its undulating 58mm Sawtooth™ rim shape with Hyperfoils™ is the most aerodynamic and stable wheel. With the Total System Efficiency™ (TSE™), Zipp's approach at combatting the biggest enemies of speed: wind resistance, gravity, rolling resistance, and vibration losses. And gravity? The 454 NSW Tubeless Disc brake is roughly a pound lighter than its predecessor! Zipp’s use of hookless rims in the 454 NSW is integral to Making You Faster. With hookless, the transition between the tire and the rim is more seamless and aero. Zipp’s hookless rims have more efficient resin distribution, which means lighter, stronger wheels. At the center of the 454 NSW is the Cognition V2 Hubset re-engineered with an updated Axial Clutch V2™ mechanism for quicker engagement, lower friction, and improved durability.
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 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.
