The Arundel Mandible Water Bottle Cage was designed with two slim pieces that grasp your water bottle like jaws, securely holding your bottle in place whether you stick to smooth roads or take the stairs at your local cyclocross race. It is constructed from carbon fiber that has been given a foam core to further reduce weight. The mounting bolts are exposed, but the clean lines of the Mandible prevent your bottle from getting caught when pulling it out. This sleek package, with minimal graphics, guarantees your water will always be there when you need it.
