Aero Garmin hanger for Cervelo P5

This is an aero box designed for mounting on the top tube (behind the headset) on a Cervelo P5. Additionally, there are cutouts specifically sized to enable the mounting of a Garmin 510 'inside' the box - just place the standard Garmin rubber band quarter turn fastener within the cutout area, then mount the box using the top tube accessory points.
