Welcome to Harviv Cycling

The clamp diameter of the mount is 31.8mm. But we ship a 25.4mm rubber insert in the package to convert 31.8mm clamp size to 25.4mm.

The Mount for Garmin is specially designed for Edge 520 and 1000. Other garmin computers can also be mounted, because the Edge 520 and 1000 are heavier than other models, needing a stronger mount to hold. It has no problem for practical running and testing with garmin edge 520 1000.
