Got a flat on your 26-inch mountain bike or cruiser? This Kenda inner tube is a reliable and affordable replacement. It's designed to fit 26-inch wheels with tire widths ranging from 1.90 to 2.35 inches, which covers a lot of common bike tires. The valve is a 32mm Schrader valve (the same kind as on car tires), which is sturdy and easy to pump up at any gas station or with a standard floor pump. The tube itself is made from pressure-tested butyl rubber, which is the standard for durability and air retention. It has a 'low head' design, which just means it's a bit lighter and uses less material. The tube comes packaged and ready to go. Origin is Taiwan, a major producer of quality bike components. Always a smart idea to keep a spare or two in your garage or backpack for those unexpected punctures. Simple, effective, and gets you back on the trail or road.
