An apparatus is provided to reduce the aerodynamic drag of bicycle frame mounted water bottle and cage systems. Furthermore, the apparatus also improves the safety of bicycle water bottle and cage systems. In an exemplary embodiment, a cage and bottle are provided. The cage is formed with a plurality of hemispheres which can spread apart in order to receive bottles of various diameters. The bottle is longer and thinner than bottles in use today and is formed with dimples on the entirety of its surface. The cap provided with the bottle has minimal threading and is formed with breaks in the threading to allow for the top to be ejected when dropped.
