Garmin Edge 540/840 Silicone Case
Garmin Edge 540/840 Silicone Case, After we've invested in our Garmin Edge 540 or 840 bike computer, we set it up for a long and happy life with the Edge 540/840 Silicone Case. This grippy case is thick enough to protect our computer from accidents drops and falls, but thin enough to still provide easy button function and sleek mount on our bike.
