This is a set of three water bottles: one from the Trek-Trek team and two from the Cofidis team. They are Elite brand bottles, each with a 550ml capacity. The bottles show some scratches, but all three appear unused, or perhaps only used for water, as there is no smell from the mouthpieces or inside. Numbers are written on the top of the caps of two of the bottles. Please consider this a used item. Thank you for looking.
