Schwalbe 18 inch Inner tube - presta/racing type valve 40mm

18 inch inner tube from Schwalbe with presta / racing type valve. The valve length is 40mm. See below for full list of tyre sizes that this inner tube is suitable for.

This is the inner tube that is used on the Reese and Muller Birdy folding bike with a Big Apple tyre. 

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.

47-355 - 18 x 1.75"
