Schwalbe Inner Tube Standard 22 Inch Dutch - DV8/44-484, 37-489, 28-490, 37-490, 37-501. Schwalbe inner tubes are reliable. Bicycle retailers value them for their high level of reliability. Each tire is inflated at the factory and tested for air tightness for 24 hours. The tire holds air pressure longer. In production, Schwalbe requires a very high butyl content and extremely high purity of the material. This allows the Schwalbe inner tube to hold air pressure significantly longer than other inner tubes. It is a group-tube system: A Schwalbe inner tube is extremely elastic and fits multiple tire sizes. This is why they are called group-tubes. For example, the inner tube with number 19A fits tire sizes from 27.5 inches to 29 inches and widths from 40 to 62 mm. Finally, the tire is 100% recyclable. Standard version: High reliability, proven for many years.
