Frequently Asked Questions
What devices can I mount with this base?
Works with any RAM arm, phone cradle, GPS mount, or accessory equipped with a 1/4"-20 threaded connector.
Does the ball joint allow repositioning without removing hardware?
Yes — the rubber ball and socket design lets you adjust the mounted device to different angles by hand, then lock it tight with the set screw.
Will this vibrate loose while riding?
No — the stainless steel hardware and rubber ball damping system absorb road vibration and maintain a secure hold.
How is this different from a rigid mount?
The rubber ball and socket isolates vibration from your bike to your mounted device, protecting phones and electronics from shock damage.

RAM Mounts products are super-high functioning
These mount under the bottom stem bases of the side mirrors and allow professional mounting of treasured farkles such as phones, GPSes, and other devices. The way you set up your base mount connections will handle everything that you add later. Lots and lots of options with RAM Mounts -- excellent.
