Zipp
454 NSW Disc Center Lock Carbon Clincher Wheel Set
Zipp engineers have optimized the biomimicry-derived 454 NSW for the ultimate in all conditions braking control ? disc brakes.
This marks the first NSW wheelset available for disc brakes, offering cyclists the greatest AeroBalance with the superior modulation and stopping power of disc brakes.
Zipp engineers studied the environment around them for instances of how nature solved similar problems of speed, control, and efficiency for the next generation of Zipp wheels. Think of a humpback whale?s fast but graceful movements thanks to the special features on the leading edge of its pectoral fins, or the unique micro texture of a shark?s skin, which gives it the ability to glide effortlessly through the water.
These structures inspired Zipp advanced development engineers to systematically apply biomimicry to solve the complex challenge of designing a wheel that reduces both aerodynamic drag and side force.
Using nature as a roadmap, Zipp began the rigorous aero development process of the 454 NSW Disc-brake utilizing the wind tunnel, CFD, and real-world testing. The result is an undulating 53/58mm-deep rim shape that takes nature?s most elegant design solutions and combines engineering precision to deliver a wheel that performs unlike any made before.
The most visually striking and functionally important biomimicry-derived innovation in the handcrafted 454 NSW Disc-brake is Sawtooth?. This patented 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 HexFin? ABLC dimples for improved airflow. Without the need for a brake track on the 454 NSW Disc-brake we were able to extend the HexFin ABLC dimples from the rim?s Hyperfoil nodes all the way to the outer edge of the rim.
This design reduces aerodynamic drag while simultaneously improving crosswind control through higher frequency wind vortex shedding. By generating a greater number of smaller, less powerful, yet more predictable vortices Zipp has engineered a wheel with superior stability. To visually compliment the rim?s aerodynamic structure without interfering with its function, our Impress? printed graphics are applied from edge to edge.
The result is Zipp?s highest performing disc-brake 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. 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.
BEYOND THE RIM
Our NSW-exclusive Cognition? Disc-brake hubset 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. And to make installation and service as quick as this wheelset is on the road, we?ve designed the hubs to use a center locking disc brake interface and J-bend spokes. Product features Use: Road?

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?
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?
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.
ImPress?
Zipp has employed the ImPress? graphics technology, which prints graphics directly on the wheel, to help allow the dimples to do what they were design to do ? help control vortex shedding, the rate at which air sheds off the wheel. Managing this is crucial to stability. ImPress graphics also give NSW a distinctive stealthy look. Zipp 454 NSW Carbon Clincher
