BICYCLE TIR LEVER TOOL This tire fitting tool makes light work of tight tire beads; simply position the slotted jaw onto the opposing rim and place the hook under the stubborn bead, then roll the bead over the rim into place. Great tool for installing MTB tires and road bikes tires. This tool will NOT damage the the rim edges because the pressing force is from the top to the bottom. Unlike traditional tire levers' leverage to install a tire will damage those weak rim edges such as carbon wheels. Length: 220mm. Weight: 120.6g
