Foam tire beader meant to help bead your back tire. Very effective and helpful for putting new tires on or flipping tires to maintain maximum traction. A must have for every serious trials rider.
I'm much too cheap to spend money when I don't have to. After fighting to get the beads to seat on my last 3 rear tires I finally gave in and bought one of these. First use, tire bead seated up in seconds and I am kicking myself for not buying it sooner.
