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.
