The Schwalbe tube No.9 fits 24" tires with a width of 28-47 mm and is used in various applications, including children's/youth bicycles, wheelchairs, unicycles, trailers, etc.

Due to their excellent manufacturing, Schwalbe tubes have proven themselves in the market for years. They are consistent in wall thickness and round in shape. Their precise construction makes them durable at the seams. A comparison test showed that the Schwalbe tube maintains air pressure significantly longer than other tubes (the others lost almost twice as much air pressure in 30 days as the Schwalbe tube). A possible reason for this could be a lower butyl content in the other tubes. The special quality of Schwalbe tubes comes from the uniqueness of their rubber mixture. To ensure this high quality, each Schwalbe tube is inflated and tested for at least 24 hours before leaving the factory.

Features:

• Butyl rubber ensures double the air retention
• 24-hour test for each tube
• High elasticity allows coverage of many tire sizes per tube
• Recycling process achieves very good energy balance
