Description
Schwalbe inner tube DV19 in the ETRTO size 40/62-584/635. Equipped with a Dutch valve with a length of 50mm.
The Schwalbe inner tubes are reliable. Every tire is inflated in the factory and is then tested for airtightness for 24 hours. The tire holds the air pressure longer. In production, Schwalbe requires a very high butyl content and a very high purity of the material. This allows the Schwalbe inner tube to hold the air pressure significantly longer than other inner tubes. It is a group of inner tubes: 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 19 for a tire size of 27.5 inches to 29 inches and a width of 40 to 62 mm fits. Finally, the tire is 100% completely recyclable.
