Breaking your aerodynamic position won't help you break any records. That's why Profile Design created the Aerodrink. With it, you're able to store your hydration between your aero extensions. So, you'll be able to rehydrate without deviating from your sweet spot. Even better, the bottle's aerodynamic shape means that you're able to achieve the aforementioned without paying a heavy aerodynamic penalty. The Profile Design Aerodrink features a 32oz 946ml capacity, and it weighs in around 171 grams. Please note that this bottle does not include the required mounting bracket. To mount the bottle to standard aerobars, Profile recommends its Universal Aerodrink Bracket. However, for narrower aerobars and base bar affixing, you'll need Profile's Aerodrink Base Bar Bracket.
