ZIPP NSW Core Sram/Shimano

No matter where you ride, the 404 NSW Carbon Clincher Tubeless is engineered to make that ride faster. With a rim depth of 58mm, the 404 NSW is designed as a do-everything wheelset that is adept at climbing and maintaining speed on the flats; a wheel strong enough to handle the Spring Classics, but light enough to inspire sprints out of corners.
The 404 NSW Carbon Clincher Tubeless features a redesigned rim shape that aerodynamically integrates wider tubeless tires for enhanced ride quality and performance. Like its 303 and 808 NSW siblings, the 404 NSW Carbon Clincher Tubeless? wider 19mm internal rim width and corresponding outer rim shape for aerodynamic optimization with 25mm tires. This wheelset allows you to run tubeless or traditional clinchers. The benefits of tubeless include superior flat protection, the ability to run lower pressures, and a smoother ride with high cornering grip and low rolling resistance.
The 404 NSW?s unrivaled crosswind stability saves watts that would have been spent keeping the bike straight, and provides unequivocal confidence for high speed descending.
When it comes time to slow for a corner, our NSW exclusive Showstopper? brake track stands ready to deliver the best modulation and shortest stopping distances available, regardless of weather conditions or the length of the descent.Simply put, the 404 NSW Carbon Clincher Tubeless represents the cutting-edge of tubeless carbon clincher wheel technology delivered straight from The Nest, where Zipp?s advanced development engineers design the world´s fastest wheels. Tires such as the Zipp Tangente RT25 Road Tubeless are a perfect match for this wheelset to deliver exceptionally low rolling resistance and high cornering grip.
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.

Technologies:

Showstopper?:
- Showstopper? is a complimenting pairing of a directional, molded-in, texture with silicon carbide particles suspended in the surface resin.

ABLC? SawTooth? Technology (Aerodynamic Boundary Layer Control):
- Our new Sawtooth dimple design consists of 12 nodes that are specifically 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.

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 design to do help control vortex shedding, the rate at which air sheds off the wheel. Managing this is crucial to stability. ImPress graphics also give NSW a distinctive stealthy look.
