Zipp has used biomimicry to take the streamlined and aerodynamic movements of natures sleekest sea creatures and applied the science behind such motion to this fantastically smooth-gliding road wheel.
|Front Axle Type:||Unknown|
|Wheel Size:||700c (622)|
The 454 NSW Carbon Tubular Front Wheel sees Zipp put innovative research and development to work in their quest to create the most fast-rolling and aerodynamic road wheel going. Based around the elegant movements of two natures fastest moving predators, the whale and the shark, they have built a rim profile that glides through road terrains just like those creatures would their watery habitat.
Looking at the leading edge of the whale's pectoral fin and the microtexture structure of the shark's skin, Zipp has taken the essence of what makes the motion of these sea creatures so effortless and applied it to the wheel in the form of its SawTooth deep-rim profile and Hexfin Aerodynamic Boundary Layer Control (ABLC) dimpling. Tested in real-life conditions and wind tunnel examinations until the desired performance was achieved, the results yielded unrivalled air-drag and side force reduction at every wind yaw angle.
A fantastically designed road wheel for ultimate speed and control, the 454 NSW Carbon Tubular Front Wheel leads by example.
The industry-leading Showstopper brake track allows you to brake later with more stopping power and greater control, regardless of weather conditions or the length of the descent.
The name given to the Zipp NSW variable depth 77/82mm rim profile. This design is the result of rigorous wind tunnel and real-world testing. The rim shape takes natures elegant design solutions and combines their precise engineering finesse to deliver a wheel that performs like nothing else before.
This technological design refers to the individual nodes that are part of the Sawtooth rim design. Each of these structures feature the Hexfin ABLC dimples that stabilise handling in gusting and strong wind conditions by increasing wind vortex shedding. The dimples create a secondary vortex around the outer rim surface, which in turn heightens the wheel control and saves rider energy from being wasted.
Hexfin Aerodynamic Boundary Layer Control (ABLC)
The 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.
