Zipp 454 NSW Carbon Clincher Wheels Information

Season : 2017

Brand : Zipp

Code : ZIPP454

Last season saw the release of Zipp's 404 NSW wheels. The development of these (and the 808's that preceded them) was a direct result of the technologies being explored for use in the 454. The reason the 454 has taken longer to reach the market is simply because, though Zipp had identified the shape they wanted to employ in their new flagship wheel, they couldn't manufacture it.

Developed using the science of Biomimicry, Zipp were able to understand how for example, a Whale is able to make rapid movements through special features on the leading edge of their Pectoral fins and how sharks are able to move effortlessly through the water thanks to structures on their skin - evolutionary fluid dynamics if you like. Ultimately Zipp have engineered similar features into their new wheel shape and surface features in order to further reduce aerodynamic drag and side force.

The 454 NSW's most obvious feature is it's shape - Zipp call this Sawtooth and it is the most important functional aspect of the wheels. The biomimetic Sawtooth shape gives rise to a rim with varying depth, from 53mm to 58mm, this novel shape gives a reduction in both aerodynamic drag and a simultaneous reduction in side forces. Each rim section or node that transitions from 58 to 53mm is referred to by Zipp as a Hyperfoil and in conjunction with Zipps new evolution of their ABLC dimples - HexFin, is responsible for reducing the size and therefore power of vortices leaving the rim. The hexagonal shape, variable size and fin-shaped arrangement of the HexFin dimples reduces (to a greater degree than circular dimples) the boundary layer mixing of air across the surface, allowing the wheel to move through the air with greater efficiency.

Ultimately, the Hyperfoil shape dramatically improves the stability of the rim, particularly at greater yaw (off-centre) angles, giving the wheels the reactivity and handling characteristics of a much shallower rim (between 30 and 35mm) this saves the rider energy by reducung the effort to control the wheels in gusty conditions. The variable sized HexFin ABLC dimples further enhance this control while literally helping the rims slice through the air. Fast and stable.

Each rim takes 12 hours to produce and once finished is laced, tensioned and built by hand onto Zipp's Cognition hubs. Cognition hubs use an axial magnetic clutch design that reduces drag at the hub by 50% over traditional 3 Pawl systems when freewheeling. What this means is a quieter and more efficient freehub when free-wheeling, as well as a more positive and definite drive when you are putting the power through the pedals. The way this works is by totally disengaging the clutch when there is no forward pedal motion, but as soon as you begin stomping on the pedals again there is near instantaneous engagement.

Along with the new hubs, Zipp's aptly named ‘Showstopper’ brake track features on the 454 NSW. Made using Silicon Carbide for the best braking performance in all weathers, it almost eliminates brake fade on even the longest of descents. On top of this a more subtle change has been made to the graphics on the side of the rim, Zipp have begun using a trademarked ImPress graphic. This new design has allowed the company to print logos directly on the surface of the rim, which not only improves the overall aesthetics of them but minimises disruption to the HexFin Dimples.

All in all the 454 NSW wheels represent a huge leap forward in rim design and real-world benefits : offering huge stability benefits without compromising speed will improve bike response and reduce fatigue for all riders in a broad range of conditions. When the wind picks up and everyone else is rolling on their 30mm rims you'll be sitting pretty on your 454s taking all the performance gains that go with them.

The 404 NSW are an excellent choice for any road racer, tester or Triathlete.
