Have you been tormented by the age-old question, “Is this more, or is this more aero?” Now you can rest easy, because we have your answer – the Profile Design Aero HC System is the pinnacle of aerodynamic hydration. How did they do it? They put the bottle in the most aerodynamic place on the bike (between the aero bars), made the bottle aero, made the straw aero, and left room for your cycling computer behind the bottle, so it’s out of the wind and out of the way. It’s as easy as that. Featuring a flip cap for easy re-fill and no splash, a removable nose to aid in the cleaning process, and a BPA-free bottle, this is your aerodynamic hydration solution.
