Zipp 808 Carbon Clincher Front Wheel 2019

Zipp 808 Carbon Clincher Front Wheel. The Zipp 808 Carbon Clincher Front Wheel delivers superior aerodynamics and top level performance. Primarily designed to shine on the road for racing, this wheel is superbly fast and thanks to Firecrest rim technology and its unique 82mm ABLC SawTooth dimpled and deep profiled surface, this deep section aerodynamic rim provides exceptional crosswind stability Fast, Stable and Enhances Your Cycling Experience. This wheel provides exceptional speed thanks to its instant power transfer and boosts rider confidence and safety thanks to its performance enhancing stability. The 82mm rim depth significantly increases aerodynamics and thanks to the ABLC Sawtooth rim profile. it handles crosswinds exceptionally well. For a wheel equipped with a rim of this depth, the stability and potential speed it can carry is unmatched by any other wheel design in this category; it truly is a marvel to ride and will enhance your cycling experience Features Rim Material Carbon Rim Type Clincher Rim Depth 82mm Rim Width External 26mm; Internal 17mm Dimple Surface ABLC SawTooth Hub Zipp 77 Spoke Count 18 Spoke Lacing Pattern Radial Spokes Sapim CX Ray Bearings Cartridge, stainless steel Max Tyre Pressure 125 psi Weight 830gFeatures Showstopper Showstopper is a complimenting pairing of a directional, moulded in, texture with silicon carbide particles suspended in the surface resin. The current media blast process applied to all Zipp rims increases the surface roughness of the brake track providing the rider with consistent and responsive braking. In order to improve this for the wettest of rides, Zipp have introduced a moulded in groove specifically tuned for the Zipp Tangente Platinum Pro EVO Brake Pad. The grooves have been optimized to interact with leading edge relative to the rotation of the wheel of the brake pad and the four cooling channels. The leading edge of the pad and first two channels efficiently wipe water and debris outward, cleaning and drying the braking surface, while the second two cooling channels have maximum interference with the grooves allowing greater braking force than a smooth rim. The cleaning effects of the groove and pad interaction improve brake feel and consistency even in dry conditions. Hexfin Aerodynamic Boundary Layer Control ABLC The 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. Firecrest A unique to Zipp rim profile that provides more aerodynamic finesse than any other rim design. It also improves handling in crosswinds significantly and increases the ride quality enormously. Visco Elastic Constrained Layer Control VCLC Using a vibration absorbing material that is compressed between layers of solid carbon laminate on the rim surface. This technology means that when the rim receive an impact from the road, a lot of the shock is absorbed by the VCLC system, resulting in a 10% reduction in road vibration. Wire EDM Electron Discharge Machining allows Zipp to precisely remove internal material from the rear hub after they have been heat treated. This removes any abnormality that can sometimes occur during the heat treating process, resulting in perfectly finished hub shell. SawTooth The name given to the Zipp NSW variable depth 5358mm rim profile. This design is the result of rigorous wind tunnel and real world testing. The rim shape takes natures elegant design solutions and combines their precise engineering finesse to deliver a wheel that performs like nothing else before.
