The Arundel Sport Water Bottle Cage is a nylon-reinforced plastic version of the famous Arundel Dave-O carbon cage. The Sport will hold all sizes of bottles securely and will last the life of your bike. It weighs 50g, about 20g heavier than the average carbon cage, but the upsides are its style, and its substantial cost savings. The Sport also has two sets of mounting holes to allow the best fit for your frame. The Arundel Sport Water Bottle Cage is available in the following nylon injection molded colors: Black, Blue, Red, and White.
