The Sparrow Cage is made from a single sheet of lightweight 5052 alloy. The Sparrow's wings fold in to securely cradle your water bottle and the cut outs help keep the cage light. Get a Sparrow or two and make your ride fly. Works well for many different water bottle shapes, and even holds a metal water bottle nice and securely.
