The Schwalbe tube No.19 is suitable for 27.5", 28", and 29" tires with a width of 40-62 mm. It is used in both touring trekking 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 perfectly round in shape. Their precise construction ensures durability at the seam. A comparative test showed that the Schwalbe tube maintains air pressure significantly longer than other tubes (the others lost nearly twice as much air pressure as the Schwalbe tube in 30 days). A 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 checked for at least 24 hours before leaving the factory.

Features:

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