You are bidding on a brand spanking new, in box Set of ZIPP’s new 454 NSW Carbon Clincher wheel set. 100% of the proceeds will go to World Bicycle Relief – mobilizing people through the power of bicycles.
Zipp’s new 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 keep an eye on.
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, keep an eye on, 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 go with the flow 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 concurrently 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 along side 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.
The 454 NSW’s undulating Sawtooth™ rim architecture with HyperFoils™ represents the next evolution of the Sawtooth™ ABLC dimple technology found on all of Zipp’s NSW wheels. The HyperFoils™ and HexFin™ ABLC dimples help to stabilize handling in gusting wind by increasing wind vortex shedding frequency. Lower frequency shedding produces larger, more powerful vortices. In cycling terms, this unstable situation is frequently referred to as “buffeting.” 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 keep an eye on, 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. Providing extra confidence, Zipp’s industry leading Carbon Clincher technology is durable and reliable, with no heat-related failures.
The 454 NSW also features our industry leading silicon carbide Showstopper™ brake track that lets you brake later with more stopping power and greater keep an eye on regardless of weather conditions or the length of the descent. Zipp’s ImPress™ NSW graphics technology, which prints graphics directly onto the rim, reduces weight and helps the HexFin™ ABLC dimples to do their aerodynamic job Whilst elevating the wheel’s visual allure to new heights.
BEYOND THE RIM SHAPE
Making use of our NSW-exclusive Cognition™ hubset, 454 NSW® rolls efficiently whether you are pedaling or coasting. Our Axial Clutch™ technology allows the freehub’s ratcheting mechanism to deliver half the mechanical drag of conventional three pawl hubs. Assembled with Swiss bearings made to our exacting specifications, the Cognition™ hubset is as robust as it is fast.
Each Indianapolis-made 454 NSW® rim requires 12 hours to create and represents a true blending of hand craftsmanship and advanced manufacturing techniques. After each rim is laid up, molded, drilled, printed, and inspected, every wheel is assembled and tensioned entirely by hand in Indianapolis. 454 NSW® rims are laced to our Portuguese-made Cognition hubs using Belgian Sapim® CX-Ray spokes and Secure Lock nipples for unmatched performance and reliability that is made to last.
This is the shape of things to come. This is 454 NSW®.

World Bicycle Relief (WBR) was founded in 2005 by F.K. Day and Leah Missbach Day in response to the 2004 Indian Ocean tsunami. As a founder of SRAM and leader in product development, F.K.’s role offered a unique opportunity to problem-solve with other cycling industry leaders. As a documentary photographer, Leah’s gift for sharing stories helped bring the devastation of those affected by the tsunami to light. Together, with a solid backing from SRAM Corporation and an outpouring of beef up from industry leaders, FK and Leah helped to launch WBR and provide bicycles to those in need. Partnering with aid organizations in Sri Lanka, WBR distributed more than 24,000 bicycles to displaced survivors, providing access to education, healthcare and livelihoods Whilst reconnecting entire communities.
Following the positive have an effect on that bicycles provided as relief in Sri Lanka, we were invited to partner with a large-scale health program in Zambia. The USAID-funded program, RAPIDS, trained and equipped community healthcare workers to help combat the AIDS epidemic. In 2006, we provided more than 23,000 bicycles through this program to beef up volunteers who would walk long distances to provide home-based care.
WBR has since built programs to provide specially designed, locally assembled bicycles for students, healthcare workers and entrepreneurs across Africa, South America and Southeast Asia. Whilst the bicycles themselves help individuals conquer distance and increase their carrying capacity, WBR has also created new economic opportunities by training field mechanics and employing bike assemblers to beef up our local programs.
