The Schwalbe Tube No.4 fits 16" and 18" tires with a width of 28-37 mm and is used in children's bicycles, strollers, 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. Thanks to their precise joining, they are durable at the seam. A comparison test found that the Schwalbe tube maintains air pressure significantly longer than other tubes (the others lost almost twice as much air pressure as the Schwalbe tube over 30 days). A possible reason for this might 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 individual Schwalbe tube is inflated and checked 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 very good energy balance
• Now also available with the new Schwalbe Clik Valve
