Cyclists, this Dexnoca tire repair kit is an absolute must-have for your bike bag! With 30 years of manufacturing experience behind them, they've packed everything you need into this compact case. You get 21 vulcanizing patches in different sizes (8x 1.18 inch rounds, 16x 1.47 inch rounds, and 8 rectangular patches) plus 6 pre-glued 1-inch patches for quick fixes. The four metal rasps/scuffers help you properly prepare the inner tube surface for a permanent repair that actually bonds with the rubber. Everything stores neatly in a lightweight portable box that weighs just 3 ounces - perfect for tossing in your backpack or bike bag. Works on pretty much any inflatable rubber tire including road bikes, mountain bikes, motorcycles, BMX, ATVs, wheelchairs, and even rubber boats! The vulcanizing patches create a permanent repair that becomes part of the tube, unlike those temporary sticky patches that peel off. Whether you're dealing with nail punctures, glass cuts, or other road hazards, this kit has you covered. Dexnoca stands behind their products with excellent customer service too. Don't get stranded - this repair kit could save your ride!
