Zipp 808 NSW Carbon Road Disc Rear Wheel 2019

Zipp 808 NSW Carbon Road Disc Rear Wheel. Favoured by professionals and thrillseekers alike for its raw speed capacity, this 808 NSW rear wheel from Zipp includes disc brake compatibility for braking power to match the sheer speed this wheel offers. Featuring a sharp, ultra deep 82mm rim depth for incredible aerodynamics, the rim surface also utilises ABLC SawTooth technology for excellent crosswind stability and reduced high yaw drag Modern Racing Hub. This rear wheel also includes Zipp's Cognition hub, a modern breakthrough in hub design that utilises powerful magnets to disengage your freehub's ratcheting mechanism, cutting down automatic braking and allowing you to retain speed control around corners Features Hubs Cognition Disc Rim MaterialCarbon Rim Width Internal19mm Rim Width Outer26 4mm Rim Depth82mm TypeClincher Tubeless 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 950g 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. ImPress While some brands will sacrifice a little function for form, this technology from Zipp ensures you get a wheel that works as good as it looks. Graphics are printed directly onto the wheel, freeing the dimples to control vortex shredding and maintain your stability to the optimal level BuyZipp Wheels & Tyresfrom Chain Reaction Cycles, the World's Largest Online Bike Store.
