Zipp 454 NSW Carbon Tubular Front Wheel 2019

Zipp 454 NSW Carbon Tubular Rear Wheel. Studying nature and its seamless ability to adapt to its surroundings and environments, Zipp has taken the movements and behaviours of a variety of land and sea creatures and used them as inspiration for this fast and efficient front roller Nature Inspired, Precision Engineered Front Road Wheel. In the research and development of the 454 NSW Carbon Tubular Front Wheel, Zipp has taken to biomimicry, inspired by the elegant movements of the whale and the shark, to create a rim profile that glides through road terrains just like those creatures would underwater. The leading edge of the whale's pectoral fin and the micro texture make up of the shark's skin as they slice through water currents was the main takeaway that Zipp put into this wheel. Achieving an undulating 5358mm deep rim, they rigorously tried and tested the wheel under strenuous conditions until it produced its desired performance Culminating in unrivalled air drag and side force reduction at every wind yaw angle, the time and effort spent researching this 454 model has resulted in a fast rolling front wheel that will set you atop the podium Technologies Showstopper. 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 SawTooth. The namegivento the Zipp NSW variable depth 7782mm 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 Hyperfoil. This technological design refers to the individual nodes that are part of the Sawtooth rim design. Each of these structuresfeaturethe 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 HexfinAerodynamic 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 Features.
