Zipp 454 NSW Carbon Clincher Disc Brake Rear Wheel
Description
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. Engineering Precision Using whales fast but graceful movements thanks to the special features on the leading edge of its pectoral fins, or the unique microtexture of a shark’s skin, which gives it the ability to glide effortlessly through the water. Zipp took this research and applied it to their wheel rim profile. 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. Reduces Aerodynamic Drag and Side Force 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 patented rim shape achieves something conventional aero wheels cannot; it simultaneously reduces both aerodynamic drag and side force. SawTooth: 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. 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. 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 variably sized dimples that work in concert with each Hyperfoil™ of a Sawtooth™ rim. Each Wheel Includes: Zipp Tangente titanium black QR skewer Zipp valve extender Zipp individual wheel bag Zipp Tangente tube 700c x 20-28mm Zipp rim tape 700c x 20mm Zipp thru-axle end caps to fit 12x142 dropouts
