Fidlock Bottle Twist Uni Base Mount The Fidlock Bottle Twist Uni Base Mount is used with Fidlock's Bottle Twist bottles (sold separately) to create a magnetic-mechanical mounting system, unlike any standard bottle and cage. The system does away with a conventional water bottle cage, allowing the bottle to be attached to any part of the frame. A simple twist of the bottle is all that's required to secure or remove it from the frame. Features Magnetic-mechanical mount takes up little space on the bike Ability to mount bottle anywhere on frame allows the bottle to fit in the smallest frame configurations Individual Fidlock bottles available at an inexpensive price point | Fidlock | Bottle Twist Uni Base Mount Uni Base | Plastic
