Zipp 454 NSW Carbon 2018 Wheel Set

Zipp 454 NSW Carbon 2018 Wheel Set. Carbon wheel set forn clincher with classic brake or disc brake.

Zipp 454 NSW Carbon 2018 Front Wheel. Carbon front wheel for clincher with classic brake or disc brake.

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. 

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.

COGNITION HUBSET

Every time a conventional hubset starts to coast, friction within the freehub ratchet mechanism works like a drum brake to slow the rider down. With Cognition’s Axial Clutch™ technology, we’ve reduced this drag by disengaging the ratchet mechanism when coasting. With less internal hub drag a rider can pedal less when drafting in a headwind, achieve higher speeds when coasting in an aero tuck, or opt to stop pedaling a moment sooner before entering a corner and bank that wattage for use exiting the corner. Axial Clutch technology also allows riders to maintain speed through corners that don’t require braking input, thereby increasing corner exit speeds.

ABLC SAWTOOTH

Our new Sawtooth dimple design consists of 12 nodes that are precisely clocked to start aerodynamic shearing at a rate of 50hz at a rider speed of 20mph. Sawtooth accomplishes this by inducing small sheet vortices that shed at a low magnitude, but at a higher natural frequency, thus decreasing the laminar bubble effect on the aerodynamically shielded side of the rim’s profile to further reduce high yaw drag and improve crosswind stability. That crosswind stability then imparts peace of mind when the weather turns south while saving watts that would have been expended while attempting to hold your line.

IMPRESS

We’ve employed Zipp’s ImPress™ graphics technology, which prints graphics directly on the wheel, to help allow the dimples to do what they were designed to do – control vortex shedding, the rate at which air sheds off the wheel. Managing this is crucial to stability. Like the 808 NSW, ImPress graphics also give the 404 NSW a distinctive stealthy look while keeping the rim as light as possible.

SHOWSTOPPER

When it comes to braking, “good for a carbon rim” wasn’t good enough for the 404 NSW. We wanted braking performance that was better than aluminum rims, and we’ve achieved that goal. Our industry leading silicon carbide Showstopper™ brake track delivers unmatched stopping power and modulation regardless of weather conditions or the length of the descent. With Showstopper™ braking performance, you’ll need to find another excuse not to ride on rainy days.
