Handlebar phone holder
Once the Stem phone holder is placed in the steering column, simply tighten the Allen screw to allow the parts to expand and firmly adhere to the walls of the steering column. Before purchasing the Stem phone holder for sport bikes, check the size of your bike's steering column, for example using a measuring tool, to ensure that the holder is compatible with your vehicle. Also note the space required around the steering column, for example, in the presence of a steering damper.
Unlike other phone holders for sports bikes, Stem is equipped with three adapters (included) that allow it to be placed on different handlebar columns with a diameter of 10 and 25.5 mm, divided into three sizes: S (10 - 15.1) - M (15.1 - 20.1) - (L 20.1 - 25.5).

Shock and vibration damping
The rubber ball can absorb some of the low-frequency vibrations coming from the engine or the road (bumps, holes, porphyry) and transmitted to the handlebars. With less vibration propagating to the cell phone port, there is less risk of damaging the components present in the latest generation of cell phones.
