Suitable for road, mountain, and triathlon bikes, the Mandible will help you stay hydrated on any ride. With an elegant design and form it has created a smooth surface on which the bottle can pass as its being released from its cages, without snagging or catching. With two, thin arms the Mandible has a smaller contact area for grasping a bottle yet with its strong carbon fibers and unique design gives up to 40% more grasping power than other cages. Not only is it strong but with a foam core this cage&';s structure is incredibly light. The Mandible Water Bottle Cage comes in one size with a weight of 28g.
