Designed for severe racing conditions dominated by steep climbs, wicked winds, and the need for immediate acceleration, the technology-packed 303 significantly diminishes muscular road fatigue without sacrificing the convenience of clincher tires.

The high performance 303 Clincher incorporates a bundle of significant enhancements, including Zipp's latest improvements to ICT carbon fiber processing, and the maturation of performance and comfort enhancing VCLC technology.

In all, the 303 clincher is an outstanding choice for fast riders demanding lightweight, aerodynamics and great overall ride characteristics with the convenience of clincher tires.

New for 2006, the 303 clincher has been redesigned to take advantage of Zipp's patented dimpling technology.

Using M2CM technology, a hand-crafted Carbon rim is wed to a totally new alloy extrusion resulting in an aerodynamically superior 40mm deep clincher rim that's over 100 grams lighter than the average 30mm deep conventional alloy rim.

For the first time on a structural carbon fiber rim, custom post machining finishes each rim to ensure a perfectly parallel, machined aluminum braking surface to provide sure and dependable braking.

Lateral stiffness is more than double that of traditional rims while the vertically compliant carbon element ensures a comfortable riding experience over all too common rough roads.

Zipp's exclusive VCLC technology dramatically reduces rider fatigue, particularly in the hands, arms, neck, and posterior - while greater control of the tire contact patch simultaneously improves cornering grip and minimizing rolling resistance.

Clincher tires exhibit different aerodynamic properties than tubular tires, so we subtly alter the shape of the clincher profile to maximize the aerodynamic characteristics of clincher tires. The clincher rim is completely new with further enhanced aerodynamics, resulting from careful shaping of the rim profile to match popular tire brands and widths. As a side bonus, the new rim shape is over 15% stiffer without any weight penalty.

Zipp's patented regenerative airfoil makes the rim appear deeper when slicing into headwinds, while improving cornering control by appearing shallower to side winds.

The 303 wheels are ideal for criteriums and excel in road racing.

Triathletes or lightweight riders desiring a wheel with minimal reaction to cross winds will also find the 303 Clincher a fine choice.
