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.

Manufacturers code: SV4

About Schwalbe :

SCHWALBE, with world headquarters in Reichshof-Wehnrath, Germany, is the foremost bicycle tyre company in Western Europe.

1911 - With a business partner, Ernst-Wilhelm Bohle sets up the bicycle manufacturer Phillips. It is the coronation year of George V. The German emperors arrive for a fifteen-day state visit in Great Britain.

1983 - Bohle creates a legend: The Schwalbe “Marathon”, Germany’s first long lasting tire with high quality puncture resistance.

2000 The Schwalbe "Marathon" becomes the benchmark by which other tires are measured. As globetrotters like Wolfgang Reiche, who crossed five continents by bike in four years, trusts in the reliability of the long runner. Today this classic from the Schwalbe range is the most-sold Touring and Trekking tire in the world.
