OVERVIEW An all new between the arms bottle design packed full of features and functionality. The HSF/Aero HC 800+ has been designed to incorporate all the essential features required of an aerobar bottle system along with a couple of premium add-ons. Flexible hose with bite valve and magnetic retention. Garmin mount on the cage / removable. New mounting bracket with greater compatibility than previous models. New cage with high retention design splash back. Rear piece can be unscrewed for easy cleaning. Secure fill port lid to avoid splashing. Additionally, the shape of the bottle has been designed to hide the cage from the wind. We worked to minimize frontal area wherever possible to avoid adding aero drag to your setup. Performance
