Zipp’s 303 S 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 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 groundbreaking wheelset also features all-new cosmetics setting the rider apart from the pack and comes at an attractive price. FEATURES Zipp graphics and cosmetic identity that scream speed Fastest with 28mm fits wide gravel tires as well 76 / 176 DB hubs with Center 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.

THE DESCENDANT Building on the success of the Full-9 along with feedback from trusted athletes and featuring new technologies we developed in-house the Full-10 Spherical was engineered to be the new standard in DH fit protection and style. Created in the Bell+Giro testing Dome in Scotts Valley CA our proprietary Spherical Technology™ powered by Mips® features a ball-and-socket design that helps redirect impact forces away from the brain allowing the outer liner to rotate around the inner liner during a crash. In addition the Spherical Technology channels inside the lightweight unidirectional carbon shell allow us to achieve superior ventilation like never before — what we are calling our Thermal Exchange Airflow System™ (T.E.A.S.). This system sucks in cool air like a vacuum and then expels hot air through the side and rear exhaust ports because as any rider knows ventilation and sweat management go hand-in-hand. With the Full-10 the effort is evident — from Ionic+™ antimicrobial* comfort padding and magnetic cheek pads to an integrated breakaway camera mount and titanium D-rings on the chin strap. This work has all been for you the rider because when you are in the start gate or at the lip of the jump that will launch you to glory we want you to only be thinking about the ride ahead.

Zipp 303 S Carbon Disc Rear Road WheelTaking its design from the higher-spec Firecrest 303 model, this rear wheel is ideal for modern "go anywhere" road bikes. Zipp has also updated this model with a wider rim to improve rider comfort, handling and aerodynamics. Expanding greatly on its heritage of conquering the Spring Classics, this 303 wheel maintains its ideal-for-every-terrain 45mm rim depth. However, this model 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 optimise rider performance on this new breed of bike. This wheelset is tubeless compatible and designed for disc-brake bikes, allowing the ability to run wide tires at lower pressures for race-ready speed on or off the tarmac.45mm Deep Rear WheelThe 303 S is among Zipp's lightest wheels, optimised for top aero performance with a 28mm tyre but capable of handling gravel tyres up to 50mm wide. The key innovation is in the 303 S's rim design. Its 45mm rim depth is the same as its predecessor, the 302 Disc brake. But its external rim width is 2mm wider, at 27mm, and its tyre bed is a full 7mm wider, at 23mm internal width. That rim platform is designed to be the fastest with a 28mm tyre. The wide rim optimises tyre profile to allow lower tyre pressure. That helps to reduce rolling resistance and provides a more compliant ride. The result of all this is a 10 watt savings vs. a top peer wheel in total power required to ride 40kph on a flat road with a 28mm tyre, according to internal Zipp testing.This ground-breaking wheel also features all-new cosmetics, setting the rider apart from the pack, and comes at a very attractive price.Please Note: Shimano/SRAM freehub option is for 11 speed Shimano/SRAM XD cassettes.
