More water or aerodynamic advantage? You used to have to choose, but with the Vision Drink System, you can have your cake and eat it too. It's a super-cool system made just for time trialists and triathletes. It gives you the ability to put two different drinks in one hydration unit and comes in a handy aero design to help you cheat the wind. Which is pretty darn awesome if you think about it.
Composite carbon fiber reservoir tank saves weight and looks amazing
Two separate molded bladders with their own straws let you carry both water and a hydration drink
Drink tubes are equipped with flow valves to make drinking easier
System fits between Aerobar extensions with minimum 55mm of separation (measured inside to inside)
