Unlike other needle type tools that have the release opening on the side, this tool has the split right in the center. You simply push the tool directly into the puncture and pull straight out. No bending, twisting, or looping is necessary. A twist of the Rasp tool inserted into the needle eye releases the plug. It's a tried and true method. You can Stop & Go too. This kit is for general use on all tubeless tires. Five re-enforced rubber Insert Strips, Rasp tool, Split-eye Insertion tool, and a .41 fl. oz. tube of Rubber Cement are all included in this inexpensive yet very effective kit.
