This is a Garmin mount made using 3D printing from Glass filled Nylon designed to hold the 200/500/510/800/810 or 1000 Garmin in the middle of a pair of contact slr integrated handlebars. This mount bolts onto the underside of the stem using the two bolts that should already be in place. Please ensure that your bars have the two location points under the stem prior to purchase. Bolts are also supplied in case they are not currently in place. These mounts are special order and will take up to 10 days to produce. They also have a Di2 junction mount holder located underneath.
