The Arundel Carbon Cage is the envy of many a rider, but when your budget calls for a bit more modesty, its Sport Water Bottle Cage provides the same security for your bottle, at a fraction of the cost. Weighing a mere 20 grams heavier than the carbon version, the Sport Cage is nylon-reinforced plastic designed to wrap your bottle securely. Two sets of mounting holes mean that it will fit virtually any frame.
