The Schwalbe Tube No.19 fits 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 round in shape. Their precise assembly makes them durable at the seams. A comparative test showed that the Schwalbe tube maintains air pressure significantly longer than other tubes (the latter lost almost twice as much air pressure as the Schwalbe tube over 30 days). A potential reason for this could be the 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 checked 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 a very good energy balance
