DESCRIPTION 360-Degree Swivel Ball Design Adjustable ball mount base provides the possibility to adjust the angle as you need. You could adjust the angel to not contact the gas tanks when your motorcycles turn left or right. Hold Your Drink Firmly There are 12 rubber gears on the top of cup holders, which will keep your drinks steady and solid so that they won't pop out on a bumpy road. We suggest that the drinks and beverages you put in need to be more than 1.97 inches in diameter.
