The Zipp 303 is a favorite all-around wheel for many riders. The 44mm rim depth of the 303 is 12mm less than the Zipp 404 allowing the Zipp 303 to be lighter and perhaps lend it better handling properties in crosswinds. They are the perfect choice for riders seeking an aero benefit, but who still like to have a lightweight advantage for climbing and experiance less buffeting in crosswinds.
The Zipp 303 is built with Zipp's Carbon Bridge technology that dramatically increases impact resistance with a Kevlar thread running perpendicular to the carbon laminate on the tire bed of the rim. Between layers of carbon in the rim construction lies Zipp's VCLC system, which uses a shock-absorbing material to reduce vibration by 10%. The VCLC system also helps your wheels stay glued to the pavement under all conditions. The most amazing thing about the 303's is you get all the aerodynamic benefits at a very low weight of 653 grams for the rear tubular or 1182 grams per pair.
