Zipp 808 Firecrest Carbon Road Front Wheel 2019

Zipp 808 Firecrest Carbon Road Front Wheel. A wheel that prioritises speed without factoring control will be the difference between a won race and a lost race. Zipp's 808 Firecrest balances both forces to give you an optimal wheel that gives back as much as you put in. A carbon fibre rim means aerodynamic performance without weighing down your bike and an 82mm deeper rim depth means better drag performance and increased stability. Plus, a wider rim means improved ride quality and greater rolling resistance management. All this results in a wheel that builds on Zipp's innovations with an eye to improving racer control Excellent Cornering Road Wheel. With the Cognition hubset, featuring Axial Clutch technology, you can maintain higher speeds even when approaching corners, thanks to an innovative ratchet mechanism that disengages as you coast. Combine this with a hubshell design that keeps bearings in place even under high radial spoke tension and you have a front wheel that saves you precious seconds and grants you the opportunity to edge ahead without risking damage to your bike All New Braking Power. Zipp's ShowStopper technology brings new durability and function to the rim brake, taking advantage of suspended silicon carbide particles within the rim texture for increased braking power even in tougher conditions Features Hub Model Cognition RimClincher Tubeless Ready Rim Width28mm Rim Depth82mm Brake Track Width 26 4mm SpokesSapim CX Spring Spoke Hole Count18 Hole Spoke PatternRadial Max Tyre Pressure125psi 8.62bars Dimpled SurfaceABLC SawTooth NipplesSapim Secure Lock Weight857gTechnology ShowstopperShowstopper 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. SawToothThe 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. 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.
