The Schwalbe tube No.6 fits 20" tires with a width of 28-40 mm and is used in children's bicycles, strollers, 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 joining makes them durable at the seam. A comparative test showed that the Schwalbe tube holds air pressure significantly longer than other tubes (the others lost nearly 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 arises from the uniqueness of their rubber compound. 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 double the air retention
• 24-hour test for each tube
• High elasticity allows coverage of many tire sizes per tube
• Recycling process achieves a very good energy balance
