Zippâs 303 S Tubeless Disc-brake wheelset aims to provide cyclists with âthe versatility they demand with the speed they crave.â
The 303 wheelset maintains its âideal-for-every-terrain 45mm rim depthâ but adds a significantly wider internal width. This aims to provide greater performance and ride quality.
Zipp adds that 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 tyres at lower pressures for ârace-ready speed on or off the pavement.â
The 303 S is among Zippâs lightest wheelsets, optimized 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 Sâs 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.
The rim platform is designed to be the fastest with a 28mm tyre. The wide rim claims to optimize 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 claimed 10 watt savings versus a top peer wheel in total power required to ride 40kph on a flat road with a 28mm tyre, according to internal Zipp testing.
