The Schwalbe Tube No. 7 fits 20" tires with a width of 40-62 mm and is used for 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 are uniform in wall thickness and round in shape. Their precise construction makes them durable at the seam. 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 in 30 days). A possible reason could be a lower butyl content in the other tubes. The special quality of Schwalbe tubes arises from the uniqueness of their rubber blend. To ensure this high quality, each individual Schwalbe tube is inflated and inspected for at least 24 hours before leaving the factory.

Features:

• Butyl rubber ensures double 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
• Now also available with the new Schwalbe Clik Valve
