The Schwalbe tube No.20 Extra Light fits 28" (or 27" –630) tires with a width of 18-25 mm and is used in racing bikes, lightweight cross and trekking bikes, etc.

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

Thanks 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. Due to their precise alignment, they are durable at the seam. 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 in 30 days as the Schwalbe tube). A possible reason for this could be a lower butyl content in the other tubes. The special quality of Schwalbe tubes comes 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:

• Extra Light – significantly lighter with the same durability (65g)
• Butyl rubber provides double 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
