So I gave these Motion Pro tools a try today for the first time BeadPro Tire Bead Breaker
So will it break the bead on the rear wheel of the Adventure? Yep sure will, quite well in fact. You have dick about a bit to get "fork" part in far enough, but it once there it pops it off straight away.
Is the lever part any good? Not really to broad and flat - I reverted to my normal spoons.
