Profile Design’s Aero Drink System is an affordable and efficient hydration system for those times when you are in the aero position on the bike. It attaches in-between the aerobars where you can easily rehydrate and not have to mess with water bottles sitting on the frame. The splash guard poly web plug keeps your drink in your mouth and from splashing around. Great for training and races. Comes with splash guard poly, extended soft straw and cap. 32. oz capacity. Optional Aerodrink Bracket Adapter for most split Profile Design bars sold separately.
