RAM Mounts are a secure and effective way to mount your DoubleTake mirror, GPS, Camera, SPOT, IPOD, Phone, and/or any other do-dad, widget, or farkle to your bike. You use a mount where you want to place your item, a mount and/or cradle on the item, and an arm in between the two. Snug up the knob on the arm and you’re set.
If you're buying to use with the uber-cool DoubleTake Adventure Mirror we suggest the 3" (RAM-B-201U) if you're not sure what length you need as they offer the most adjustment. That said, we usually rock the 2" (RAM-B-201U-A) as we're a little different. Still, we would never suggest anyone refer to us as role models.
