The Arundel Mandible Water Bottle Cage was designed with two slim pieces that grasp a water bottle like jaws, securely holding the bottle in place whether we stick to smooth roads or take the stairs at our 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.
