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.
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 often 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 control, 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 allows you to brake later with more stopping power and greater control 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 while 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®.

Approximately 4-10 working days depending on country
via Parcelforce Signed Delivery (fully traceable service). Please add items to the basket to calculate delivery for desired country.
If your country isn't listed for delivery at checkout please contact us.
Delivery of Bikes
We ship all our bikes free of charge within the United Kingdom (excl. Jersey and the Channel Islands at this time) and all our bikes come pre-assembled with just a few tweaks required (Please see our Bike Build Instruction page for details of assembly required).
All our bikes undergo a safety check before being re-boxed for shipping which can during busy periods take a little longer to complete so whilst we aim to ship all our bikes within two working days of the order please allow for additional time for this process.
All our consignments irrespective of the carrier require a signature upon delivery, deliveries are typically made between 08:00 and 18:00 so please bare this in mind when choosing a delivery address.
We do try when possible to reuse packaging from our own suppliers in order to send purchased items to our customers, we ask if the packaging is still in good condition after you've received your goods then please try to use it again or recycle if not possible.
