Zipp 303 Tubular rear wheel 2011
Perhaps the most versatile wheelset in our line, the light and aero 303 is well suited to hilly road races and smaller riders looking for control in windy events.
Small but still with an aero advantage.
Especially with 23-25mm tires, the 303’s width also provides a significant aerodynamic advantage over narrower rims – even ones with much deeper profiles. With a fully toroidal aero shape, the 303 did its part to help Fabian ride solo for 40 windy miles at Flanders and Roubaix and build up a combined margin of victory of more than 3 minutes, including the victory celebrations. Despite its aero performance, the 45-mm rim depth and ABLC™ dimples keep the 303 stable in crosswinds.
Built tough without the weight.
The 303 owes its toughness to a 27.5mm-wide rim profile designed to absorb bumps by flexing like a leaf spring. This improves on the already superb impact resistance of Zipp’s Carbon Bridge™ technology while offering a comfortable, forgiving radial compliance. At the same time, the wide rim increases the 303’s lateral stiffness for sprinting, cornering, and accelerations.
