The Schwalbe Tube No.19 fits 27.5", 28", and 29" tires with a width of 40-62 mm. It is suitable for both touring trekking bikes and mountain bikes.

Due to their excellent manufacturing, Schwalbe tubes have been successful on the market for years. They are consistent in wall thickness and round in shape. Their precise joining makes them durable at the seam. A comparison test showed that the Schwalbe tube maintains air pressure significantly longer than other tubes (the latter lost nearly twice as much air pressure as the Schwalbe tube in 30 days). A possible reason could be a lower butyl percentage in the other tubes. The special quality of Schwalbe tubes results from the uniqueness of their rubber compound. To ensure this high quality, each 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
