ZIPP 303 S Tubeless Disc A1 Rear

The Zipp 303 S Tubeless Disc A1 rear wheel 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 Zipp 303 S Tubeless Disc A1 rear 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 Zipp’s lightest wheelsets, optimized for top aero performance with a 28mm tire but capable of handling gravel tires up to 50mm wide.

The Zipp 303 S Tubeless Disc A1 rear borrows design concepts from the higher-level 303 Firecrest Tubeless Disc-brake wheelset to gain speed through increased efficiency. The result is a wheel with reduced: Wind resistance, rolling resistance, 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, but its rim width is 2mm wider at 27 mm and its tire bed is a full 7mm wider, at 23mm. The rim platform is designed to be fastest with a 28mm tire and optimizes tire profile to allow lower pressure, which helps reduce rolling resistance and improve compliance.

What does all of this mean? The Zipp 303 S Tubeless Disc A1 rear boasts 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.

Choosing the right set of wheels for your bike can provide a significant performance enhancement and add aesthetic appeal. If you have questions about which bike wheel and tire combination will be best on your ride, please reach out to us for advice or shop more Zipp products with NOMAD.
