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.

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.
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 1x11 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.

Zipp Speed Weaponry was founded in 1988 with the sole mission of making athletes faster on their bikes. Over the course of the last two decades, Zipp has done exactly that, by drawing on its core competencies of design engineering, composites knowledge, and wind tunnel development. It is these competencies that have allowed Zipp to deliver a series of firsts in the cycling industry. From the first carbon disc wheel to the first carbon crank to the first wheel to achieve negative drag in the wind tunnel. These firsts have helped Zipp athletes to become champions in the toughest races in the world, on the fiercest roads in the world, from the cobbled roads of Belgium to the Queen K in Kona.
