Zipp 404 NSW Carbon Tubeless DB Rear Wheel. This 404 NSW all carbon rear wheel has been designed to give your bike every advantage come race day. Featuring a deep 58mm clincher rim, this wheel has an excellent aerodynamic profile while remaining remarkably lightweight. Plus, thanks to Zipp's Sawtooth ABLC rim texturing, this wheel offers consistent and stable performance even in tough crosswinds. Disc Brake Compatible Hub. With its disc brake compatible Cognition hub, this 404 wheel gives you responsive braking and consistent power transfer in equal measure. Featuring Axial Clutch technology, the Cognition hub automatically disengages your ratcheting mechanism while coasting to give you more speed and control on every turn 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 Weight 840g 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.
