Zipp 404 NSW Carbon Road Disc Front Wheel 2019

Zipp 404 NSW Carbon Road Disc Front Wheel. If you're looking for a clincher wheelset that promises powerful race day performance and control, look no further than this 404 NSW front wheel from Zipp. Featuring an extra deep 58mm carbon rim, this wheel takes advantage of an excellent aerodynamic profile while remaining lightweight. Additionally, thanks to Zipp's Sawtooth ABLC rim texturing, this wheel stays fast and stable even in tough crosswinds. Advanced Hub Design. This 404 wheel features Zipp's Cognition hub, which utilises innovative Axial Clutch technology to disengage your freehub's ratcheting mechanism automatically while coasting for maximum speed retention. This hub also features disc brake compatibility for incredible braking power in all conditions Features Hubs Cognition Disc Rim MaterialCarbon Rim Width Internal19mm Rim Width Outer26 4mm Rim Depth58mm TypeTubeless Ready Max Tyre Pressure125 psi Dimple SurfaceABLC Sawtooth Technology Brake InterfaceDisc Brake Spoke Count24 Spoke TypeSapim CX Ray J Bend Spoke Lacing Pattern2 Cross NipplesSapim Secure Lock J Bend Weight760g frontTechnology Hexfin Aerodynamic Boundary Layer Control ABLCThe 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 rims profile to further reduce high yaw drag and improve crosswind stability. ImPressZipps ImPress graphics technology prints graphics directly on the wheel, which allows the dimples to do what they were designed to achieve, to control vortex shedding and the rate at which air sheds off the wheel. Managing this is crucial to stability. ImPress graphics also give NSW a distinctive stealthy look BuyZipp Wheels & Tyresfrom Chain Reaction Cycles, the World's Largest Online Bike Store.
