LazyBone: Stem Cap Mount
This is it, the lightest mount for a Garmin 200, 500, 510 or 810 at 3 grams. It's half the weight of the OEM mount, more secure, protected, centered and a better view angle. Includes integrated tether attachment loop for the Edge 510 and 810. Mount it and forget it. .
LazyBone fits all 1 1/8th diameter steer tubes and is carbon safe. It will accommodate most low or normal stem cap profiles.
