More info

Schwalbe 20 inch inner tube for tyres with width of 1 1/8 and 1 3/8 inch diameter.

Why choose this inner tube from Schwalbe?

Schwalbe test all the inner tubes that they make (twice), including an inflation test for 24 hours to ensure that the tube maintains its air pressure.

Less lost air means less time inflating and more time for you, whether it's riding, in bed before work or at the office.

Manufacturers code: AV7A
