The Schwalbe Tube No.12 fits 26" or 27.5" tires with a width of 32-47 mm and is used in Mountain Bikes, City/Trekking Bikes, E-Bikes, etc.

Due to their excellent manufacturing, Schwalbe tubes have proven themselves in the market for years. They have uniform wall thickness and are round in operation. With their precise assembly, they are durable at the seam. A comparison test showed that the Schwalbe tube maintains air pressure significantly longer than other tubes (the latter lost almost double the 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 special quality of Schwalbe tubes results from the uniqueness of their rubber blend. 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 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
