Schwalbe 20 x 1.5-2.5 inch Inner Tube – Schrader Valve

The Schwalbe 20 inch inner tube is constructed from a high quality, Butyl rubber compound for ultimate durability and a long life span. The tube features a Schrader valve which has been chemically bonded to the tube for optimal air pressure retention for a smooth riding experience. Each individual Schwalbe tube is inflated and placed into a specifically designed mold and put through a vulcanising process to ensure consistent wall thickness for impressive air pressure retention.
