Zipp 303 Carbon Clincher Front Wheel 2019

Zipp 303 Carbon Clincher Front Wheel. The Zipp 303 Carbon Clincher Front Wheel provides high end, podium proven performance and is fully ready to tackle any riding style you can present it with. Featuring a lightweight, super stiff and durable construction, which is perfect for spending all day climbing in the hills without you ever feeling weighed down, but inspires rider confidence with its responsiveness and control to ensure you can race your way to the bottom at full speed and be in complete control. This full carbon wheel features the unique Showstopper brake track surface, which provides exceptional stopping power and brake balance in even the wettest of weather conditions while not decreasing your brake pads wear life Aerodynamic Performance. The 303 Firecrest wheel design is fine tuned and optimised thanks to rigorous wind tunnel testing to ensure that air drag does not affect stability or your power output when aiming to increase your performance. The power transfer is increased further thanks to the precise wheel building procedure that all Zipp wheels are subject to. Every Zipp wheel is laced and constructed by hand and tuned to the highest levels of performance; many World Tour events have been won on Zipp wheels and customers receive the exact same quality as their Pro Race Teams Features Hub Model 77 Rim Outer Width 26 4mm Rim Internal Width 17mm Rim Carbon Clincher Rim Depth 45mm Spokes Sapim CX Sprint Spoke Hole Count 18 Hole Spoke Pattern Radial Spoke Length Drive 260mm Max Tyre Pressure 125 psi Dimpled Surface ABLC Sawtooth Nipples Sapim Secure Lock Weight 645gTechnologies 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 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 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 Buy Zipp Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
