The Aero30 aero-bar mounted hydration bottle is designed to be the most aerodynamically efficient way to carry fluids on a bicycle. Designed with new Xflow3 spill-free, fill-on-the-go-cap, patent pending AeroFlow straw and dual channel mounting system, the Aero30 will keep you fast and hydrated. CLEANING: After each use, to clean your bottle, simply fill with a few drops of liquid dish soap and warm water and shake vigorously. In addition you can use a thin bottle brush to gently clean out the corners at the bottom. Please take care when inserting a bottle brush.
