The Rib Cage II is a sleek, lightweight water bottle cage designed to be fast in the wind while reliably holding bottles secure during rough riding conditions. The cage features a super-low bottle position that improves aerodynamic profile and a tuned compression design that provides secure bottle retention with easy in-and-out accessibility. The reinforced composite material construction improves durability without adding weight. The SWAT(TM)-compatible design allows for storage and tool integration, accepting both SWAT(TM) Cage Mount Road or MTB Tool and MTB SWAT(TM) Box when used on compatible frames.
