Bike retailers appreciate them for their high reliability. Every tire is inflated at the factory and tested for airtightness for 24 hours. The tire holds air pressure longer. In production, Schwalbe requires a very high butyl content and very high purity of the material. This ensures that the Schwalbe inner tube holds air pressure significantly longer than other inner tubes. It is a grouped inner tube system: A Schwalbe inner tube is extremely elastic and fits multiple tire sizes. This is why they are called grouped inner tubes. For example, inner tube number 19A fits tire sizes from 27.5 inches to 29 inches and for widths from 40 to 62mm. Finally, the tire is 100% fully recyclable. Extralight version: Just as reliable, but with a low weight.
