Speedfill Bike Hydration System The Speedfil Hydration System is a revolutionary cycling product designed to enhance athlete hydration and aerodynamics. The wind tunnel developed, frame mounted system, smoothes airflow around the frame while the rider is in motion. The rider is able to maintain an aerodynamic position all the while drinking up to 40 ounces (1.3 liters) of fluid. Hydration is immediate as a bite valve and tubing keep fluid at the ready for whenever it is needed. Other unique features of the Speedfil include user ability to refill the system on-the-fly, which minimizes the need for additional bottles, as well as a unique dual splash resistant opening that allows for rapid refills with minimal fluid splashing. All speedfil bottles are made from FDA compliant high density polyethylene and are safe for their designed use Features Aerodynamic – Wind tunnel developed Easily refillable on the fly 40oz. + fluid capacity (1.2 liters) Frame Mounted to optimize handling and minimize drag Exclusive dual splash resistant design Hands free drinking Bite valve holds fluid at the ready Less weight and clutter than multiple bottles Available in Down Tube & Seat Tube mount configurations Bottle and Cage Specification Length: 12"(+/-) Width:2"(+/-) Height:9"(+/-) Volume: 40oz.
