The Bar Fly TT mount is designed for triathletes and time trialists. It allows a variety of mounting options along either side of your aero extensions so you can easily keep an eye on your computer.
The 1/8th-turn design allows compatibility with both Garmin Edge computers and the Garmin Forrunner 310XT and 910XT watches without looking at your screen sideways or needing to adjust the orientaion of the mount when you switch between devices. (To mount the watches, you will need the appropriate quick release kit, available separately.)
