Zipp wheels have been the choice of top-level triathletes and cyclists for over twenty years now and their new 404 NSW Carbon Clincher Rear Wheel is their benchmark in terms of aerodynamics, performance and technology. Utilising the technology that saw their 808 NSW wheelset take gold at the Ironman World Championships in 2015, this wheel applies this design to Zipp's most popular rim depth; 58mm.
This rim depth has been developed in the American Manufacturer's secret test lab to provide riders with improved braking performance, exceptional aerodynamic efficiency and unparalleled crosswind stability. The advanced aerodynamics of the wheel has been developed using 42 different computational fluid dynamic concept studies to provide optimal crosswind stability that saves watts that you can use to put back down onto the road. This heightened level of aerodynamics also adds confidence in fast descents as you know you can rely on the wheel for snappy and fast responsiveness.
Slowing for corners is not an issue with this wheel as the 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.
Zipp's new Sawtooth dimple design consists of 12 nodes that are precisely clocked to start aerodynamic shearing at a much higher rate than regular flat wheels. This acts in a similar manner to the dimples on a golf ball to create tiny vortices that act to displace air and allow the wheel to pass through with less drag.
At the centre of this amazing rim is the Cognition hub. Every time a conventional freewheel coasts, friction within the freehub mechanism creates drag and works like a drum brake to slow you down. The Cognition uses the new Axial Clutch technology to reduce internal freehub drag by using magnets rather than steel springs to engage the lightweight ratchet rings. A star-flanged straight-pull hub shell design on the rear hub distributes the load placed on the hub flange away from the bearings.
The NSW 404 rear Wheel is finished with sleek Impress graphics that are printed directly onto the rim's surface. This helps to maintain the dimples aerodynamic effect while also giving the wheel a sleek, stealth appearance.
