SCHWALBE No.8 Tube 22"

The Schwalbe 22-inch inner tube, available in all valve types, fits children's bikes with the rather rare 22-inch tire (children's Dutch bicycle, intermediate size) and is extremely stable in air pressure! The rubber compound makes it possible: less air leakage means less pumping. Extremely reliable and with quality control for safe riding pleasure: Every Schwalbe tube is tested twice at the factory for air retention.

Stable air pressure: A Schwalbe tube simply holds air much longer. The quality of the ingredients and the purity of the rubber mixture determine the quality of the tube even at the material stage. During vulcanisation, every Schwalbe tube is placed in a mould and pumped up. This is the only way to ensure uniform wall thicknesses and excellent air retention.

Reliability: The consistent control ensures the highest possible functional reliability: each tube is pumped up at the factory and stored under pressure for 32 hours to check for air retention.

Group tube system: Due to the high elasticity and quality, a single tube covers many tyre sizes. For example, tube no. 17 works as well with a tire width of 28 mm as with a tire width of 47 mm. Only an extremely high-quality and reliable tube can meet this requirement.

Valve types: Tubes are available in three different valve types (SV, AV DV), the correct choice depends on the application and the diameter of the rim hole (8.5 or 6.5 mm).
