The HSF BTA offers maximum versatility and minimal approach to putting a bottle between your arms. Lightweight, retaining, and integrated computer mounts with set-back mounting points, give you everything you need and nothing you don't. The mount is offset so that the center of the bolt is located sufficiently behind the mounting point. This allows you to set the cage/bottle further behind even the aerobar where you can't reach the bottle once you pull the bottle forward. The mount has a slightly offset V-shape that fits snugly between the extensions, reducing the risk of bottle interference even in narrow armrest settings. This mount supports more extension widths than conventional models The HSF BTA improves positioning versatility and holding power, allowing you to mount a Garmin computer on top of the bottle Construction: Injected Nylon/Glass Fiber Compatibility: HSF Bottle or General Cycling Water Bottle Computer Compatibility: Garmin Mount (Removable) Mount Offset: 30mm Mount Drop: 10mm Extension Width: 80mm to 120mm(C-C) Color: Matte Black Weight: 100g
