Compatible with motorcycles with 22mm diameter steering stem. It tends to rattle things out of place and wear things down. Vibration is especially bad when it breaks things that are not designed to withstand it, such as your GPS, cell phone, MP3 player, camera, radar detector or that other expensive gizmo that you have mounted on your bike. This is why we created the AdaptivMount. The AdaptivMount is specifically designed to minimize the vibration transferred from your bike to your gadget with the patent-pending AdaptiSorb Anti-Vibration Technology. Traditional mounts have a single top plate that transfers vibrations directly from the bike, through the mount, right to your gadget. The AdaptivMount, however, is designed with two plates separated by AdaptiSorb vibration dampers. Your gadget mounts to the top plate only. With this design, the vibrations are absorbed through the dampers before they reach your expensive gadget. Choosing a mounting system has always been a tradeoff between adjustability, ease of installation, aesthetics, size, and vibrations. With the AdaptivMount, you get it all. The double ball-joint design provides a high degree of freedom for optimal positioning, easy adjustment, and simple installation. High strength steel and aircraft grade aluminum components ensure a sturdy connection, while the AdaptiSorb Anti-Vibration technology protects your gadgets in a sleek, compact design.
