The SP Connect UNIVERSAL BIKE MOUNT can be attached to any handlebar or stem with a diameter between 22 and 42mm (0.9 to 1.65 inches). If you use the mount with the arm, you can adjust the angle of your smartphone.
Without the arm you have very 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.
Please note: Manufacturers can sometimes change the specification of the products from time to time.
