$186 Between the arms (BTA) systems are a great way to stay hydrated on the fly, and some systems can even make your bike faster by adding some aero properties to your cockpit. Profile Design offers a number of aero hydration systems, including the HSF Aeria Ultimate that allows you to create a “superbike” aerodynamic front end to any bike. This aero water bottle integrates with ProfileDesign’s Aeria Ultimate Stem for a fully integrated hydration system that will make your bike even faster. The system uses a “no splash” fill port so you can easily restock your hydration needs on the fly, a magnet mount that keeps the straw easily accessible, a bite valve so it’s easy to grab a drink when you need it, and a removable computer mount.
