Zipp 303 S Carbon Disc Tubeless Frontwheel_x005f_x000D_ Zipp 303 S Tubeless Disc Brake wheelset provides today 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._x005f_x000D_ Speed for all Roads ahead: the 303 S Carbon Clincher from Zipp_x005f_x000D_ 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 Zipps lightest wheelsets, optimized for top aero performance with a 28mm tire but capable of handling gravel tires up to 50mm wide._x005f_x000D_ 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._x005f_x000D_ This groundbreaking wheelset also features all-new cosmetics, setting the rider apart from the pack, and comes at an attractive price.Product features_x005f_x000D_ Use: RoadModel: 303 S Carbon Clincher RearwheelRim size: 28″Tyre type: ClincherSpokes: 24Brake type: Center Lock DiscTubeless system: YesMax recommended system weight: 115kg (body weight + bike + equipment)Max tire pressure: 5.03bar (73psi)Outer witdh: 27mmInner width: 23mmRim depth: 45mmValve hole: SV (6.5mm)Hub: Zipp 176DHub axle system: 12 x 100 mm thru axleSpoke type: Sapim CX-SprintSpoke pattern: 2-crossNipple type: Sapim secure-locGreutate:_x005f_x000D_ 819g (manufacturer information)_x005f_x000D_ _x005f_x000D_ _x005f_x000D_ _x005f_x000D_
