16 / 18 inch bicycle inner tube with Clik Valve Tube 40mm presta / racing type by Schwalbe

Schwalbe Clik Valve Tubes. Retains air for an above-average length of time. Thanks to the best material quality and uniform wall thickness. Maximum reliability that has proven itself millions of times over.

Update: As from 2022 this is the inner tube used on the (most) P Line (Performance Line) range of Brompton folding bikes and will fit the T Line if you don't want to stay with the Tubolito inner tubes

If you have one of the following Brompton models:

• A Line
• C Line
• Pre-2022

you should use an AV4 inner tube (or use an adapter to allow this to work with your rim)

16 inch inner tube from Schwalbe with presta / racing type valve. See below for dull list of tyre sizes that this inner tube is suitable for

Riding a small wheel with a small valve hole? This is the tube for you weighing in at just 85g

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 is the same size inner tube as the Brompton one, but with a presta/racing type valve. With a valve hold convertor it is possible to use this tube on a Brompton. 

This inner tube fits ETRTO tyre sizes as shown below:

• 37-340 - 16 x 1 3/8" and 400 x 35A
• 28-349 - 16 x 1 1/8"
• 37-349 - 16 x 1 3/8"
• 28-355 - 18 x 1 1/8"
• 35-355 - 18 x 1.35"

This inner tube is also used on some wheelchairs.
