1.4 liters of water. 140.6 miles of winning.  The Ventum One’s patented design includes a water bottle that is integrated into the top tube of the frame. Integrating the bottle into the frame reduces aerodynamic drag and makes the Ventum One the only bike that is faster with a water bottle than without. The bottle holds 1.4-liters and comes with a drinking straw and a bite valve, so you can stay hydrated without ever leaving your aerodynamic position. After you take a drink, simply let go of the straw and it will be guided back on to your aero bars using the included magnetic clip system.
