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 bikes, trekking bikes, and more.

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

Due to their excellent manufacturing, Schwalbe tubes have been successful in the market for years. They are uniform in wall thickness and round while rolling. Thanks to their precise bonding, they are durable at the seam. A comparison test revealed that the Schwalbe tube maintains air pressure significantly longer than other tubes (the others lost almost twice as much air pressure as the Schwalbe tube in 30 days). 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 compound. To ensure this high quality, each individual Schwalbe tube is inflated and inspected for at least 24 hours before it leaves the factory.

Features:

• Extra Light – significantly lighter with the same durability (65g)
• 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
