Replacement Disk for Garmin Edge Aero Mount.
So you crashed? No worries, the aero mounts are meant to break at the disc, to make sure that your computer isn't the one taking the damage! If this is the case, just grab another disc, screw it in, and hit your next ride hard!
Garmin only. This disc is for the Garmin Edge Aero Mount, and will not work with any of the other mounts. Double check before you buy!
