The all-new FC35 Drink System from Profile Design is a low-profile, between-the-arms (BTA) hydration system designed to improve bike handling. The super-sleek FC35 system moves the complete volume of the hydration water bottle between the rider's arms. This weight shift helps stabilize the bike and improves aerodynamics. The airfoil shaped FC35 hydration bottle is BPA-free, holds 35 ounces of fluid, and has a patent-pending no-splash refill port. The system includes an integrated computer mount and rear air foil storage system. Brand new from 2015, the Profile Design FC35 Hydration System blends aerodynamics, power and comfort.
