FIDLOCK BOTTLE 590ML WITH TEX BASE TRANSPARENT BLACK"Sometimes smaller is better. For example, when the bike has a very narrow frame in which a conventional bicycle bottle has no place. This is where the TWIST bottle 590 comes into play: it fits into the smallest frame triangles, not only because of its smaller volume, but also because of its clever, space saving bottle design. Here, the bottle is attached to shoulder straps or similar areas."
