Staying hydrated while cycling is crucial to your performance. Using a cycling water bottle is the most convenient way of carrying liquids while cycling as you can just pop it into the water bottle cage on your frame and out of the way and use when needed. The bottles are made from plastic with a wide lid for refilling and an easily resealable bite top for use on the move. They are available in a variety of sizes from 500ml upwards but all share the same width dimensions so will fit in any bottle cage so long as there is room on your frame. Some models offer better insulation or more innovative bite valves for longer distance events or use with aero bars. To stop tools or spares sagging in your back pocket there are also storage bottles available with a flat watertight lid which fit in the bottle cage.
