ASC Computer Mount Ultegra Di2 Countered even more for betterThe ASC computer mount is compatible with 43 & 52 ASC series extensions (not ASC Pro) and with Garmin mount systems. With its low weight and minimized frontal area it is optimized for performance while providing enough adjustment to fine tune the viewing angle. This bike computer mount is designed for Garmin 500 and 800 series products. Using it with 1000 series products may result in wrist interference, causing the bike computer to tilt.
