XLAB's Torpedo Carbon Cage is designed specifically for their horizontal aero bar hydration mounts. Use with a standard bottle or XLAB's new Torpedo model (mounts and cages sold separately). The cage is made of ultra-light carbon, holds bottles securely and is super easy to use. It features a 5-pound grip force on bottles so they stay put over even the roughest roads.
