We have talked many times about the reliability, quality and flexibility of Ram Mount products. With the complete base X-GRIP Large Phone Mount With Double Socket Arm Tough-Claw, however, we go one step further. Apart from the fact that you do not need to wonder what combination of top & bottom base and arm you need, this product will free your hands if you have more than one motorcycle or you are also a cycling fan. With two moves, the Tough-Claw caliper grips (with absolute safety) on the handlebars of the motorcycle or other tube with a diameter from 15.87 to 38.1 mm. Piece of cake.
