Why choose this inner tube?

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.
