The Aero Energy Caddy is a sleek, aerodynamic top-tube-mounted bike bag ideal for triathletes and gravel racers. It's made from durable woven nylon and features three simple Velcro straps to fit a variety of bikes. A zippered opening offers easy access to its 0.7-liter storage, in addition to quick-access side pockets. Two rivets at the base of the bag allow it to be bolted to bikes equipped with threaded top tube mounting holes (bolts not included), and the straps are removable. It's fully water-resistant and its sleek look complements today's modern bikes.
