Tubeless ready for top-notch traction, this 58mm deep-rim carbon-construction rim offers durable and lightweight performance to keep you ahead of the chasing pack. Keeping a streamlined and speedy design, the wheel is dotted with Sawtooth dimples, reducing drag by efficiently shedding air and reducing side force with every rotation.
Emblazoned with ImPress branding that doesn't impact on your streamlining and aluminium Cognition Hubs which also cut down on air-drag, Zipp has made sure this wheel does everything except hold you back as you home in on finish lines and PBs. Crosswind stability and phenomenally low rolling resistance make this 404 model a must-have for those seeking second-shaving superiority.
The name given to the Zipp NSW variable depth 77/82mm rim profile. This design is the result of rigorous wind tunnel and real-world testing. The rim shape takes natures elegant design solutions and combines their precise engineering finesse to deliver a wheel that performs like nothing else before.
Hexfin Aerodynamic Boundary Layer Control (ABLC)
The 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.
