Inner tube narrow 20 inch by Schwalbe - schrader valve

Schwalbe 20 inch narrow inner tube with schraeder / car type valve

This isn't the tube you want for a Brompton G Line - you need a Schwalbe AV7

Why choose this inner tube?

Because not all inner tubes are the same.

Schwalbe test all tubes (twice), including inflation for 24 hours to ensure they don't lose 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.

This inner tube fits ETRTO tyre sizes as shown below:
28-406 - 20 x 1 1/8"
32-406 - 20 x 1 1/4"
35-406 - 20 x 1.35"
