Profile Designs HSA 800 EVO Hydration SystemThe Profile Designs HSA 800 EVO Hydration System is an update of the HSF AERO HC 800 with improved Garmin placement and a refined rear cap mechanism. It has been designed to incorporate all the essential features required of an aerobar bottle system along with a couple of premium add-ons. There is a flexible hose with bite valve and magnetic retention. There is a removable direct Garmin mount. The new mounting bracket has greater compatibility than previous models. There is a new cage with high retention. The rear cap can be removed for easy cleaning and the secure fill port lid to avoid splashing. 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. The mount is offset so that the center point of the bottle bolts can sit well behind the attachment point. This allows the cage/bottle to be set further back on aerobars that would otherwise force the bottle forward to the point where it is inaccessible. The BTA mount has a slightly dropped āVā shape to help center it between the extensions and reduce the risk of the bottle interfering with narrow armrest positions. The mount accommodates a 40mm range in extension spacing.723660011888
