Sometimes, we find that starting from scratch is the most direct route to efficiency. Sure, Profile Design has provided the tools to build up its Aero HC System from individual pieces, but if you need the most efficient triathlon hydration right now, you simply can"t beat the Aero HC. This system"s accompanying bottle features a BPA-free plastic construction and about every aerodynamic trick in the book. You"ll notice that the nose of the bottle is rounded like a bullet in order to create a minimal drag profile. Along these lines, Profile Design also created a shrouded straw mount, and even the refilling flip cap features an aerodynamic design. To secure the system, Profile"s bracket mounts to your extension bars, leaving room for you to place your bottle between the extensions. This means that you"re able to remain tucked over the extensions while hydrating, so you"re never forced to either increase your profile or sacrifice control of the bike. Additionally, the bracket features an adjustable width of 140mm, and the length of the bracket and computer mount are also independently adjustable. That"s right, we said computer mount. Profile incorporated a mount near the aft portion of the bottle, keeping your computer shielded from airflow. Basically, this system is a portable command center for speed. The Profile Design Aero HC System is available in the color Black and in one size. Please note that this system is also compatible with Profile"s Basebar Bracket attachment, and that it has a 80-120mm width from center-to-center. Additionally, the bottle is BPA-free, and it has a 28oz (828mL) capacity.
