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 bikes, wheelchairs, unicycles, trailers, etc.

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

Features:

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