The Kinetic Twenty20 Bottle Cage ergonomically improves the simple act of grabbing a drink on the bike. A natural arm motion removes and replaces a bottle at an angle of approximately 20 degrees off-center. The Twenty20 Bottle Cage can be mounted on a bike frame at a 20-degree offset left (fig. 1 in diagram), right (fig. 3) or centered (fig. 2) allowing bottle insertion into the center of the cage, rather than in from the side. They’re great for small frames and mountain bikes too. Kinetic Twenty20 Bottle Cages are made of durable polycarbonate composite and weigh just 38 grams. Available in black, white, red and Kinetic Green.
