Review on KoolStop Black Tire Bead Jack by David Perez

Well I've used this tool a few times when replacing flat pads and it has stretched the tire bead. I got the impression that this is good, but not really necessary. I could use my hands just as quickly. However, I installed a brand new tire on my bike today and this is where this tool really excels. I used to be afraid to put on new tires. No longer. With a little practice, you can easily fit a new tire to your bike with this tool. I wish I had bought this many years ago. From the photo it looks like it won't last. Although it's made of plastic, it's very durable. He had no trouble keeping up with the torque required to get the rim through the rim. I even used it on the first bead by slightly moving the hoop. For the second bead I used it as directed. If you change road bike tires, buy this tool!
