Make sure you have the Garmin VIRB HD Digital Camera Bike/Large Tube Handlebar/Rollbar Mount to record all the action from your next bike trip. Use the thick or thin insert so the mount fits perfectly, and your camera is locked firmly in place. Accommodating tube diameters from 0.75" to 1.5", the GARMIN VIRB Bike/Large Tube Mount can be used on additional objects, including handlebars, seat posts, roll bars, shotgun barrels and more. The mount features interlocking joints that grip in place instead of relying solely on tension. This provides a more rugged and durable, anti-vibration locking performance.
