Schwalbe 29 x 2.1 Inner Tube - Presta Valve

The Schwalbe 29er inner tube is constructed from a high quality, Butyl rubber compound for ultimate durability and a long life span. The tube features a Presta 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.
