The Schwalbe Tube No.7 fits 20" tires with a width of 40-62 mm and is used in children's bikes, trailers, BMX, trials, folding bikes, and mountain bikes. Due to their excellent manufacturing, Schwalbe tubes have proven themselves in the market for years. They have a consistent wall thickness and are round in shape. Their precise construction makes them durable at the seams. A comparative test showed that the Schwalbe tube maintains air pressure significantly longer than other tubes. One 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 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
