Crank Brothers Speed Lever I tried it once for a puncture repair and then stored it for a long time. The usage is written in English on the back of the package, but for those who don't understand, there are blogs by people who have used it that explain how to use it. Here's an excerpt from an article: ------------------- The 3-piece type is common, but it's difficult for beginners to handle, and if the tire is hard, the work doesn't go smoothly. In such cases, it's a good idea to use a different type of tire lever. Personally, the easiest to use is the Speed Lever made by Crank Brothers, a parts manufacturer. Extend the lever and hook one end onto the quick-release shaft, then insert the other end between the tire and the rim and go around once, and the tire will come off. When installing the tire, use the underside of the tip and rotate it in the same way. If you handle the part that takes force with care, you can remove and install even hard and tight tires. The Speed Lever extends the lever and hooks it onto the quick-release shaft, using it while rotating. XXX, who had been struggling with the 3-piece type lever, praised it, saying, "This is great!" However, the Speed Lever is already discontinued and is now almost impossible to obtain. As a successor to this, Crank Brothers released the Speedier Lever, which has a similar name but a completely different shape. It has a grip shape that you put your fingers into, and you can remove and install tires by moving it along the rim, just like the Speed Lever. The basic usability is almost the same, but the old Speed Lever seems easier to use for hard tires. Also, the Speedier Lever is bulky in shape, so storage is a bit of a problem. I hope the old model will be re-released, but it's probably difficult. ------------------- (The above is partially edited.)
