Zipp 303 Firecrest Carbon Clincher White Front Bicycle Wheel Size 700c

If perfection is the standard, then the 303 Firecrest wheelset delivers everything you could ask for, including a heritage forged in the Spring Classics. At the center of the 303 Firecrest Carbon Clincher is the 77 hubset, an innovation that results in improved stiffness, durability, simplicity and versatility. Zipp's original 303 Tubular made history by becoming the first carbon wheelset to win cycling's two most famous Cobbled Classics, Paris Roubaix and the Tour of Flanders. Its wider rim provided extra durability, and improved aerodynamics. That wider rim also led to the development of the revolutionary Firecrest platform, and now the revolution continues with the inclusion of the 77 hubset best in class durability and improved bearing protection with no pre load adjustment needed. FEATURES Firecrest With the new proprietary Firecrest rim shape in Zipp's 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, it improves handling in crosswinds and overall ride quality. Carbon Clincher This is the culmination of two years of intensive prototyping and testing. Zipp worked with their composites supplier to develop an exclusive heat resistant resin based on the materials used in motorsports brake systems. This proprietary technology improves heat management so substantially that all Zipp Carbon Clinchers pass stringent CEN safety standards. ABLC Aerodynamic Boundary Layer Control The patented and instantly recognizable dimpled pattern found on all of Zipp's carbon rims. ABLC smoothes airflow across the rim's surface and is tailored to every model from the 202 to the Super 9 Disc. The third generation of ABLC has up to four times more dimples than before. Visco Elastic Constrained Layer Control VCLC Vibration absorbing material sandwiched between layers of rigid carbon laminate in the rim. When the wheel receives an impact from the road, much of the shock is absorbed by the VCLC system, delivering a 10% reduction in vibration. Wire EDM Electron Discharge Machining allows Zipp to cut the materials for their rear hub drive internals after they've been hardened through heat treating, negating the warping and imprecision caused by the heat treating process. Steel Bearings Zipp is the only company specifying Swiss made highly specialized ball bearing cartridges. Working with a family owned Swiss bearing manufacturer, Zipp is able to attain a superior level of bearing smoothness and long life. Zipp ball bearings are specified to 10 millionths of an inch tolerance, guaranteeing that they are at least 2.5 times rounder and better matched than most company's high precision balls, and more than five times tighter than most precision balls.
