Lightweight 26" inner tube with Schrader valve for MTB & trekking.

The Schwalbe inner tube No. 13A Light is a lightweight 26" bicycle inner tube for tire widths from 1.50" to 2.50" (40–62-559) – ideal for MTB, trekking, and city bikes. Thanks to the special rubber compound, the inner tube loses less air, so you have to pump less often.

Weighing only approx. 170 g, the 13A Light is one of the weight-optimized inner tubes in the Schwalbe range, making it perfect if you are looking for a robust yet lightweight setup. The proven Schwalbe quality concept ensures that every inner tube is double-checked for airtightness at the factory – for maximum reliability in everyday life and on tours.

The inner tube is equipped with a 40 mm Schrader valve (AV). This allows you to easily inflate it at almost any gas station or with common floor pumps – especially practical for commuters, touring cyclists, and e-bikers.

Highlights:

• Lightweight inner tube: only approx. 170 g – ideal for sporty MTB and trekking use.
• Less pumping: optimized rubber compound with reduced air loss.
