454 NSW Carbon V1 Tubular Shimano Wheelset
The Zipp 454 NSW Tubular?s unmatched combination of superior aerodynamics and crosswind stability, inherent to the rim?s 53/58mm-deep Sawtooth? design, delivers the confidence-inspiring AeroBalance? handling riders need in variable wind conditions.
Technology Masterpiece: the 454 NSW Carbon V1 Tubular Wheelset from Zipp The new wheels also take advantage of the light weight rim structure made possible with a tubular design, for outstanding acceleration. With its Hexfin? ABLC dimple pattern optimized for each braking option, the 454 NSW Tubular delivers the lowest drag available and outstanding braking, whether you prefer disc brakes or our industry-leading all-weather Showstopper rim brake track.

Showstopper? is a complimenting pairing of a directional, molded-in, texture with silicon carbide particles suspended in the surface resin. Showstopper? is a complimenting pairing of a directional, molded-in, texture with silicon carbide particles suspended in the surface resin. The current media blast process applied to all Zipp rims increases the surface roughness of the brake track providing the rider with consistent and responsive braking. In order to improve this for the wettest of rides, we have introduced a molded-in groove specifically tuned for the Zipp Tangente Platinum Pro EVO Brake Pad. The grooves have been optimized to interact with leading edge (relative to the rotation of the wheel) of the brake pad and the four cooling channels. The leading edge of the pad and first two channels efficiently wipe water and debris outward, cleaning and drying the braking surface, while the second two cooling channels have maximum interference with the grooves allowing greater braking force than a smooth rim. The cleaning effects of the groove and pad interaction improve brake feel and consistency even in dry conditions. Beneath the textured brake track are SiC particles suspended in the resin. Silicon Carbide is nearly three times harder than hardened steel and is very abrasion resistant. Commonly used in cutting tools and grinding wheels, the SiC particles in our Showstopper? brake track ensure consistent performance for the life of your wheel. The net result is equal brake force in wet conditions when compared to industry leading aluminum rims. Showstopper technology delivers greater stopping power in wet conditions than any carbon wheel ever produced.
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 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.
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 Zipp Cognition Hubset with Axial Clutch Technology Zipp NSW
