Zipp’s 454 NSW Carbon Clincher is radical by design, evolutionary by nature. In the natural world, creatures are honed over generations to achieve a competitive edge within their environment. The result of this natural design process is adaptation − new shapes and forms that achieve a higher degree of efficiency and control.

 

Utilizing the principles of the emerging science of biomimicry, 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, for the first time, systematically apply biomimicry to solve the complex challenge of designing a wheel that reduces both aerodynamic drag and side force. 

The most visually striking and functionally important innovation in the handcrafted 454 NSW is Sawtooth™.

This patented new biomimetic 53/58mm-deep 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 wind tunnel proven 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.
