The 303 Tubular wheelset weighs about as much as 10 pairs of socks, while offering lateral and vertical stiffness that's 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.
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.
