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/trekking bikes, etc.

The Extra Light provides you with the usual quality and reliability of the standard tube while reducing weight.

Due to their excellent construction, Schwalbe tubes have proven themselves in the market for years. They exhibit uniform wall thickness and are round in operation. Their precise alignment makes them durable at the seam. A comparison test showed that the Schwalbe tube retains air pressure significantly longer than other tubes (the others lost nearly twice as much air pressure in 30 days compared to the Schwalbe tube). A possible reason for this could be a lower butyl content in the other tubes. The unique quality of Schwalbe tubes results 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 while maintaining the same durability
• 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
