Profile Design HSF/Aeroflow 900 Bottle Drink System. The Aeroflow bottles have been designed with disc brake tri bikes in mind. By moving the bottle close to the frame we can reduce the impact on steering when having a heavy bottle on the bars. The Aeroflow has been designed to work best with modular bar/stem systems. The wings are positioned to shield the aerobar clamps and round centre section of the bar from the wind. The shape is specifically designed to reduce wind drag by shielding aerobar clamps and the center bar from the wind.
