Because changing a tire often requires more than one tire iron, this kit include two 8-1/2" Tire Irons. At 8-1/2 inches (220mm) long and weighing just 4-3/4 oz., this tire iron is long enough for necessary leverage, but small enough to fit into most packs, saddlebags, or tank bags. One end is flat for holding and prying with the other curved for a better grip on the bead with rounded edges to help avoid tube pinching and tire damage. I-Beam cross section increases strength and bend resistance without added weight. Made from high quality drop forged steel then heat treated for strength and durability.
