Zipp 202 NSW Carbon Road Disc Rear Wheel 2019

Zipp 202 NSW Carbon Road Disc Rear Wheel. For those who prefer a lightweight racing wheel that doesn't compromise on speed or stability, Zipp's 202 NSW all carbon rear wheel is the perfect solution. With a sharp, 32mm deep rim and innovative ABLC Sawtooth technology on the rim surface, this wheel offers impressive aerodynamics while reducing high yaw drag for a fast performance that doesn't let up when the going gets tough. Disc Brake Compatible Hub. The featured Cognition hub utilises Axial Clutch technology, a remarkable innovation in hub design that allows your hub to interact with your freehub's ratcheting mechanism for increased speed control while coasting. Plus, the hub's disc brake compatibility means you'll have the stopping power necessary to maintain and control all that speed potential when it matters most Features Hubs Cognition Disc Rim MaterialCarbon Rim Width Internal21mm Rim Width Outer28 9mm Rim Depth32mm 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 Weight 780g 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.
