No matter where you ride, the 404 NSW Carbon Clincher Tubeless rim-brake wheelset is engineered to make your 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 Tubeless features a rim shape that aerodynamically integrates wider tubeless tires for enhanced ride quality and performance. The 404 NSW Tubeless’ 19mm internal rim width and corresponding outer rim shape are optimized 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.
zipp´s 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 ahigher 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.
The new Cognition Straightpull hubs, made of high-strength Z310.9 aluminium are extremely lightweight and offer a new freewheel body technology. The Swiss stainless steel bearings are the most precise in the entire industry. Specially developed hub bodies also distribute the load of the spokes more evenly over a larger surface to prevent torsion in the bearing area. The result is lower resistance and greater durability. The 17 mm hub axles are extremely stiff. The hub itself is milled using modern EDM technology so that 50 percent harder materials can be machined 20 times more precisely. The Cogniton hub series with Straightpull spokes offer an even higher lateral stiffness.
Showstopper technology uses a molded silicone carbide (SiC) surface brake ring for maximum wet braking performance. The result is a braking performance that is equal to that of an aluminium rim, even in torrential rain. Showstopper technology offers greater wet braking power than any other carbon wheel.
The imprint graphics not only provide valuable weight savings, but also enable a unique and durable application of the four letters most feared by the competition in cycling racing: Z-I-P-P.
