The Schwalbe Tube No.19A Extra Light fits 27.5", 28" and 29" tires with a width of 40-62 mm and is used in mountain bikes, city/touring bikes, etc.

The Extra Light delivers the familiar quality and reliability of the standard tube with reduced weight.

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 seam. A comparative test showed that the Schwalbe tube maintains air pressure significantly longer than other tubes (the latter lost almost double the air pressure over 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:

• Extra Light – over 35% lighter with the same durability
• Butyl rubber ensures double the air retention
• 24-hour test for every tube
• High elasticity allows coverage of various tire sizes per tube
• Recycling process achieves a very good energy balance
