The sleeve at the bottom of the mirror arm is inserted into the handlebar and the screw is tightened, which thickens the sleeve in the handlebar and holds the mirror in place. Any play that occurs can be reduced using the enclosed spacer sleeves. Danger: A hole must be cut into the handlebar grips, or so that the sleeve can be inserted into the handlebar end. We offer matching handles that are open at the ends so that the mirrors can be inserted without any problems. You can find the handles below the description under “recommended items”. We stand behind our products and their quality, which is why we guarantee the functionality of our items for 2 years. If the item no longer functions or is damaged within 2 years of the date of purchase, usable, we will send you a replacement free of c.
