The SP Connect Universal Bike Mount is a simple, toolless mount for use on the handlebar or stem. This mount can be attached to any handlebar or stem with a diameter between 22 and 42mm (0.9 - 1.65 inches). If you use the mount with the arm, you can adjust the angle of your smartphone. Without the arm, you have a low-profile mount. With or without the arm your phone can be used in a horizontal or vertical orientation. Your smartphone can now safely be attached to your bike with a 90° turn. You now can easily navigate or use your other apps.SP Connect Universal Bike Mount FeaturesTool-less mounting on the handlebar/stemArm for angle adjustmentOption for portrait/landscape format2 mounting optionsFor diameters of 22-42mmFor use with SP Connect Cases
