The TWIST bottle 550 compact lives up to its name: Thanks to its voluminous design, this water bottle takes up no more space than the TWIST bottle 450—yet holds significantly more liquid for when you’re really thirsty. This bottle is a perfect choice, especially for bikes with very tight frame geometries. It retains the popular design language and ergonomic grip for intuitive handling, as well as the removable dirt cap and the self-closing membrane for high water flow.
