The Assos logo water bottle is made by Tacx and features the familiar Assos branded on the body of the bottle. We offer it in the most-popular 21oz capacity. While relatively unknown for water bottles in North America, they are some of the finest made, to wit, many team logo bottles used in the European Pro ranks are these exact bottles. The solid valve design along with the right durameter plastic (not too soft, not too firm) and the integrated cap leash make them an easy choice.
