If you're one of those folks who just loves to make headway on the uphill climb, this is the wheelset for you. For on and out of the saddle climbers and speed demons on varied terrain, 303's advanced carbon rim technology means you get the very best of lightness, durability and comfort. Completely redesigned for 2006 to include Zipp's patented dimpling technology, further rim aero shape refinement and an increase in depth of 6mm, Zipp engineers have taken one of the best performing wheel sets in the family and improved on it even more. Nice stiffness and stability, yet surprisingly vibration free for such a lightweight wheel. Snappy on the incline, brilliant on the decline, and quick on curves, the new 2006 303 in tubular and clincher will no doubt be winning hearts and races worldwide. Please Note: These wheel sets except for the cyclo cross are recommended for riders that weigh 200lbs 90Kg or less. Clincher 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 thats 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. Weights 744g front, 812g rear Tubular The 303 Tubular wheelset weighs about as much as 10 pairs of socks 999g on the 650s, and 1124g on the 700s, while offering lateral and vertical stiffness thats more than double that of a traditional rim. This wheelset is the worldwide secret weapon of champions who compete in severe racing conditions dominated by steep climbs, wicked winds, the need for immediate acceleration, and the minimum possible muscular road fatigue. The legendary 303 tubular wheelsets continue to be a rider favorite! The superior aerodynamic properties of 303 rims have been refined through new shapes and tooling through the years resulting in continuously improved aerodynamics and cross wind stability. These improvements combined with ICT and VcLc technology offer a light weight wheelset whose lateral and vertical stiffness is more than double that of a traditional rim, with dramatically reduced road noise and enhanced rider control and road feel through improved tire contact patch consistency. For 2006, the 303 has been completely redesigned to take advantage of Zipp's patented dimpling technology. Zipp knows that true aerodynamic performance isn't always about going in a straight line, so we designed the 303 to heel over into and out of the corners like no other aerodynamic wheelset in the world. We achieve this by superior lateral rim stiffness and by minimizing the pressure differential from one side of the rim to the other while maximizing head on aerodynamic performance. The resulting regenerative airfoil makes the rim appear deeper when slicing into headwinds, while improving cornering control by appearing shallower to side winds. Multiple patents and unmatched manufacturing prowess make this aerodynamic technology a Zipp exclusive. The 303 wheelset is fast, incredibly light and stiff, handles great and accelerates like a rocket. It is ideal for criteriums and excels in steep or technical road racing. Multisport athletes looking for a great wheel for draft legal or technical courses especially under exceptionally hilly or windy conditions will love the performance of the 303, and may consider mixing with a model 404 rear. The 303 makes a great alternative wheel for extreme conditions like those often found at Kona in October or Belgium in March. The 303 Tubular wheelsets feature our exclusive Silica Ceramic braking surface for superior dry and wet weather performance. Zipp's thermally conductive brake pads are ideal for the Silica Ceramic braking surface and ensure great braking performance and rim longevity. Meticulously hand crafted using the most advanced production methods available, the 303 wheelset in classic tubular has been a staple secret weapon of European professionals for years, and is quickly becoming the weapon of choice for cyclists everywhere.
