The tube I received was the Specialized Brand 20X 1.5-2.3 with a metal valve stem with knurled nut to keep the valve stem out of the rim when attaching the pump. I researched the Specialized product and the metal valve stem tube is also available 20X1.0-1.5 for the Liberte' with 20X1.5 tires. A premium product.
