The RAM cradle for the Garmin Montana series was finally released recently, so I ordered one right away and put it on my mountain bike’s handlebars.
I pulled my 60SCSx RAM mount off my bike and connected the cradle to the old style RAP-274(U) RAM rail mount I already had on my handlebars. There are plenty of other options available for mounting the Montana to bikes, cars, ATVs, etc. Personally I like to keep the profile low on mounts as a safety factor, since I have a history of going over the handlebars!
You can see a small roller at the top of the cradle, which allows you to clip the Montana in without damage. All ports and the power button remain accessible, and the camera lens on the 650 series remains uncovered as well.
The unit seemed very secure on a fast downhill run. While it wasn’t the most technical ride I’ve ever done, it still had plenty of drop offs, etc., and I was left feeling pretty good about the mount’s holding power.
