Zipp 404 NSW Carbon Road Disc Wheels - XDR

. For performance and control without compromise, look no further than this 404 NSW clincher wheelset from Zipp. Each wheel features an extra deep 58mm carbon rim for a stunning aerodynamic profile. Plus, with Zipp's Sawtooth ABLC texturing on each rim, these wheels reduce high yaw drag for a remarkably stable performance, even in crosswinds. Advanced Hubset Design. With its built in Axial Clutch technology, the Cognition hubset utilises powerful magnets to disengage the ratcheting mechanism in your freehub for maximum speed and control whether you're pedalling or coasting. This hubset also features disc brake compatibility, ensuring you have the braking power to outclass the competition in any weather 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 Freehub Compatibility SRAM XDR Weight760g front, 840g rearTechnology 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.
