Universal tire demounting tool for two-wheel rims from 12-21 inches, thanks to the adjustable bead breaker lever.
As tubeless tires in particular sit incredibly tightly on the rim, a great deal of force is required when removing the tire.
Simply place the rim on the upper ring, adjust the bead breaker lever to the rim size and then remove the tire from the rim. With a tire lever (not included), changing the tire is child's play.
