Every tube is inflated at the factory and tested for airtightness for 24 hours. The tube maintains air pressure longer. In production, Schwalbe requires a very high butyl content and very high material purity. This way, Schwalbe inner tubes maintain air pressure significantly longer than other inner tubes. It is a group inner tube system: A Schwalbe inner tube is extremely elastic and fits multiple tire sizes. This is why they are called group inner tubes. For example, the inner tube with number 19A fits tire sizes from 27.5 inches to 29 inches and for widths from 40 to 62mm. Finally, the tube is 100% fully recyclable. Standard version: High reliability, proven for many years.
