Zipp Speed Weaponry 303 Tubular Wheel Set

The Zipp 303 wheel set was redesigned to be a little wider, and it is also a little deeper without changing the weight.  These changes substantially improve the already superb impact resistance of Zipp’s Carbon Bridge technology while offering a more comfortable, forgiving radial stiffness. In addition, the wider, deeper rim increases the 303’s lateral stiffness for sprinting, cornering, and accelerations.  The 303’s radical new shape with ABLC dimples yields 12 seconds of aerodynamic savings over 40km.


The 303 includes Zipp’s new 88 front and 188 rear hubs that feature oversize 17mm axles, higher flanges, and adjustable bearing preload. Steel skewers, 18 front and 24 rear Sapim CX-Ray spokes, and Swiss steel bearings more precise than many ceramic upgrades complete the package. Along with the rest of Zipp’s wheel line, the 303 wheelset is handmade in Speedway, Indiana.
