What's new with Prestalever II?
Ttesting with thousands of combinations of rims and tires - to make a great tool even better. The head has more curvature and contours for even better gliding. We've decreased the rim hook height by 40% to make installation and removal easier. The height and width of the body has been reduced by 17% to make the tool more compact, yet the strength has been increased by using larger diameter corners and a more slippery and flexible Nylon.
As you scoop the tire bead with the Prestalever, the slot underneath we call the "rim hook" naturally drops inside the rim. It prevents the Prestalever from slipping out, so you don't drop the bead. The rim hook stops the Prestalever at an easy-to-hold angle on the side of the rim. Then you simply glide the lever around the rim, and the tire peels-off as you go.
The Prestlever is made of slippery Nylon, greatly reducing the force needed to remove tires. When you're done, twist the Prestalever 90 degrees to raise the rim hook out of the rim. Our box-section design allows the twist-action to easily stop at 90 degrees so the lever slides out easily.
The same rim hook is used to install tires. Start the bead by hand, then insert the Prestalever rim hook at the point where you get tension. The curved top of the Prestalever head will be on the outside of the tire. Glide the Prestalever along the rim and the rim hook will lift the bead inside. The tire holds the Prestalever rim hook inside the rim as you install.
Certain tires have delicate beads. Tire manufacturers recommend hand-installation only. The Prestalever can be used as a "third-hand" tool. When you hand-install the bead in one direction, the tire starts lifting-out at the other end. Insert the lever at one end to hold the bead, then use BOTH hands to install the tire from the other end.
Tubless Tire Removal (or any Difficult Tire)
The Prestalever is the #1 tool for removing difficult tires. Insert a lever, but do NOT flip it yet. The rim hook will Hold the lever in place, but unlike traditional levers that hook onto spokes, the bead will NOT be tensioned. You can still fit-in more Prestalevers. Insert the levers spaced about 6 inches apart, then flip them all ... one-at-a-time. Even the toughest tires will come right off the rim in seconds.
