BH0505 tube 20x4.00/90/120-406 Schwalbe inner tube Fatbike 90/120-406 AV. Schwalbe inner tubes are reliable. Bike retailers appreciate them for their high reliability. Every inner tube is inflated at the factory and tested for air tightness for 24 hours. The inner tube retains air pressure longer. In production, Schwalbe requires a very high butyl content and very high material purity. This allows the Schwalbe inner tube to retain air pressure significantly longer than other inner tubes. A Schwalbe inner tube is extremely elastic and fits multiple tire sizes.
