Zipp 303 S Tubeless 12x100mm 700c Front Bike Wheel

SPEED FOR ALL ROADS AHEAD. Zipp’s 303 S Series Tubeless Disc Brake wheelset provides today’s cyclists the versatility they demand with the speed they crave.

• Expanding greatly on its heritage of conquering the Spring Classics, this 303 wheelset maintains its ideal-for-every-terrain 45mm rim depth but adds a significantly wider internal width to provide greater performance and ride quality in almost every measurable way.
• Road bikes are more versatile than ever, no matter the road surface, but just as fast as before.
• The 303 S offers an entirely new rim profile and design to optimize rider performance on this new breed of bike.
• This wheelset is tubeless for disc-brake bikes, allowing the ability to run wide tires at lower pressures for race-ready speed on or off the pavement.
• The 303 S is among our lightest wheelsets, optimized for top aero performance with a 28mm tire but capable of handling gravel tires up to 50mm wide.
• The 303 S Series borrows design concepts from the higher-level 303 Firecrest Tubeless Disc-brake wheelset to gain speed through increased efficiency.
• That is achieved by creating a wheel with reduced: Wind resistance, rolling resistance, rider fatigue, and weight.
• The key innovation is in the 303 S Series’ rim design.
• Its 45mm rim depth is the same as its predecessor, the 302 Disc brake.
• But its rim width is 2mm wider, at 27mm, and its tire bed is a full 7mm wider, at 23mm.
• That rim platform is designed to be the fastest with a 28mm tire.
• The wide rim optimizes tire profile to allow lower tire pressure.
• That helps to reduce rolling resistance and provides a more compliant ride.
• The result of all this is a 10 percent watt savings vs.
• a top peer wheel in total power required to ride 40kph on a smooth flat road with a 28mm tire, according to internal Zipp testing.
• This ground-breaking wheelset also features all-new cosmetics, setting the rider apart from the pack, and comes at an attractive price.
• New Zipp graphics and cosmetic identity that scream speed
• Fastest with 28mm, fits wide gravel tires as well
• 76 / 176 DB hubs with Centre locking interface
• XDR driver body option
• Wide rims optimize tire profile to allow lower tire pressure, especially with tubeless.
• The result is a larger contact patch for increase grip for confident cornering, descending, and handling in wet conditions.
• Lower tire pressures and larger volume provides a compliant ride with fewer vibrations.
• Significant watt savings when running larger tires at lower pressure.
• Wide hookless rims create a seamless transition to the tire, reducing drag.
