Does anyone know if there is a handlebar mount available for a Garmin Forerunner 310XT? I have seen some for different models but not the 310XT. Garmin's website does not show one but surely there is one. This thing is designed in part for triathletes to use, seems like there would be a way to mount this thing on a bike. The mount would need to work on a larger diameter bar. Or maybe someone has rigged one themselves that could give me some ideas. Thanks.
