Zipp 303 Firecrest Carbon Road Rear Wheel 2019

Zipp 303 Firecrest Carbon Road Rear Wheel. Four years of developmental refinements and innovations reflect the drive behind the all new 303 Firecrest road wheel. Embracing the tubeless ready change of the industry, Zipp have zeroed in on a wheel that maximises aerodynamic optimisation by moving to an all carbon fibre rim to utilise air pressure more effectively while keeping the weight of the wheel down. Meanwhile, the increase to the rim width combats rolling resistance and allows for better power transfer and an increase in traction. Hand built and with repeated wind tunnel testing, you have a front wheel that is prepared for whatever the road can throw at it After four years focussed on incrementally refining the Firecrest rim profile, Zipp bring you a standard setting breakthrough design. With its tubeless ready carbon fibre rim, this 303 Firecrest is the perfect gateway for any serious competitor looking to take their ride to the next level. Lightweight and aerodynamic thanks to the refined shape and design of the rim, it includes an increased width for an impressive reduction in rolling resistance and increased stability to complement the additional speed. With frequent wind tunnel testing, this wheel is the perfect solution for any rider who wants the key advantage on race day Breakthrough Cornering. With its innovative Axial Clutch technology, the included Cognition hubset utilises a magnetic mechanism rather than the traditional steel spring to free your bike from automatically braking when coasting. Free of all constraints, this gives your bike an edge with speed even when turning tough corners, allowing you to soar ahead of the competition Zipp ShowStopper Brake Track. Featuring Zipp's ShowStopper brake track technology, your rim brake will always perform even in the wet or dry. And with ABLC Sawtooth technology, blast through crosswinds without hesitation as your wheel's layer control manages all incoming forces with ease Features Hub Model Cognition RimClincher Tubeless Ready Rim Width26 5mm Rim Depth45mm Brake Track Width center 26 40mm SpokesSapim CX Ray Spoke Count24 Spoke Pattern2 cross Max Tyre Pressure125psi 8.62bars Dimpled SurfaceABLC SawTooth NipplesSapim Secure Lock Weight825gTechnology Firecrest With the new proprietary Firecrest rim shape in their 202, 303, 404 and 808 Firecrest wheels, Zipp wheels make a bigger difference in more ways than ever. Not only is Firecrest more aerodynamic than any other rim design, but it also improves handling in crosswinds and overall ride quality 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 the 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.
