BH0505 bib 20x4.00/90/120-406 Schwalbe inner tube Fatbike 90/120-406 AV. 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 clean materials. This allows the Schwalbe inner tube to hold air pressure significantly longer than other inner tubes. A Schwalbe inner tube is extremely elastic and fits multiple tire sizes.
