The Schwalbe Tube No.19 fits 27.5", 28", and 29" tires with a width of 40-62 mm. It is therefore suitable for both touring-trekking bicycles 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 joining makes them durable at the seam. A comparative test showed: The Schwalbe tube retains air pressure significantly longer than other tubes (the others lost almost twice as much air pressure within 30 days compared to 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 mixture. 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 twice the 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
