The Zipp 303 S Tubeless Disc Brake Wheelset offers today's riders the versatility they demand with the speed they desire. Dramatically expanding its legacy of conquering the Spring Classics, this 303 wheelset retains its all-terrain 45mm rim depth but adds a significantly wider internal width to deliver increased performance and ride quality in nearly every measurable way. Road bikes are more versatile than ever, regardless of road surface, yet just as fast as ever. The 303 S offers an entirely new rim profile and design to optimize rider performance on this new generation of bikes. This wheelset is tubeless ready 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 wheelset, optimized for maximum aerodynamic performance with a 28mm tire but capable of handling gravel tires up to 50mm wide. The 303 S borrows design concepts from the top-tier 303 Firecrest Tubeless Disc-brake wheelset to achieve speed through greater efficiency. This 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 disc-brake 302. However, 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 fastest with a 28mm tire. The wide rim optimizes the tire profile to allow for lower pressure, helping reduce rolling resistance and providing a more compliant ride. The result of all this is a 10 percent watt saving compared to a similarly sized wheel in the total power required to travel 40 km/h on a flat, smooth road with a 28 mm tire, according to Zipp's internal testing. This revolutionary wheelset also features a completely new aesthetic, which sets the rider apart from the crowd, and is offered at an attractive price.
Features Zipp graphics and aesthetic identity that scream speed Faster at 28mm, also fits wide gravel tires DB 76/176 hubs with center lock interface XDR and HG driver body option available Wide rims optimize the tire profile to allow for lower pressure, especially with tubeless. The result is a larger contact patch for increased grip for confident cornering, descending, and wet handling. Lower tire pressures and higher volume provide a compliant ride with less vibration. Significant watt savings when running larger tires at lower pressures. Wide hookless rims create a smooth transition to the tire, reducing drag.
