This is a Garmin mount made using 3D printing from Glass filled Nylon designed to hold a Mio 305/505 in the middle of a pair of integrated handlebars. This mount bolts onto the underside of the stem using the two bolts that should already be in place. They have been tested with Most Talon, Pro Stealth and Cinelli Ram bars but may work with others. 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.
