Introducing the Zipp 404 NSW

Following the success of the 808 NSW, which was ridden to victory at the Pro Men’s Ironman® World Championships and the Elite Women’s UCI Team Time Trial World Championships, Zipp is proud to launch our second component in the NSW series, the Zipp 404 NSW Carbon Clincher. Our advanced development engineers in our top-secret lab, known as The Nest, have delivered a wheelset with improved braking performance, exceptional aerodynamic efficiency, and unparalleled crosswind stability for our most popular and best-selling rim depth. Like the 808 NSW, the 404 NSW also makes use of our Cognition hubset for increased durability and exceptionally low freehub drag.

ZIPP® 404 NSW™ CARBON CLINCHER

No matter where you ride, the 404 NSW 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. With its advanced aerodynamics, developed using 42 different CFD (Computational Fluid Dynamics) concept studies and weeks in the wind tunnel; the 404 NSW’s up to 34% reduction in crosswind side force provides unrivaled stability for a rim of this depth and saves watts that would have been spent keeping the bike straight. The same stability that makes the 404 NSW fast on the flats also provides unequivocal confidence for high speed descents. 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 represents the cutting-edge of carbon clincher wheel technology delivered straight from The Nest, where Zipp’s advanced development engineers design the world’s fastest wheels.

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 the Cognition hubset’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 allows riders also to maintain speed through corners that don’t require braking input, thereby increasing corner exit speeds. Inside the Axial Clutch mechanism we use magnets, rather than steel springs, to move and engage our light weight Metal injection Molded (MIM) ratchet rings for unmatched reliability and consistent operation. With 36 points of engagement that all interlock simultaneously, there isn’t a more secure freehub mechanism on the market. hub.png

Our Axial Clutch freehub mechanism is also compatible with XD drivers. This gives riders the option to select a 10-42 cassette to assemble a 1×11 drivetrain with an equivalent range to either a compact or standard road double drivetrain. A star-flanged straight-pull hubshell design on the rear hub distributes the load placed on the hub flange away from the bearings. We’ve also developed a unique scalloped edge hubshell design for our front hub. This scalloped design maintains the bearing bore diameter when high radial spoke tension is applied. Both of these hubshell design elements ensure that bearings quietly stay in place, roll faster, last longer, and provide a laterally stiffer hub. About those bearings, we’ve chosen Swiss stainless steel bearings specially made to our specs to provide the longest lasting, lowest friction performance available.hub1

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 any other carbon rim, 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.
