Schwalbe AV 9 Inner Tube 24x1.75

The Schwalbe AV 9 inner tube is for 24-inch wheels with 1,75 tyres and has a 40 mm Schrader valve (the type used on cars). It is for touring and trekking, to replace a punctured or worn inner tube.

• Size 24 x 1,75, ETRTO 47-507: check that this is shown on the tyre sidewall
• 40 mm Schrader valve, the same type used on cars: can also be inflated at a petrol station
• Weighs just 130 g, so it does not weigh the wheel down
• Made from butyl, a material that retains air well, with 20% recycled inner tubes
• To choose: check your rim's size and valve type; they must match

Schwalbe was established in Germany in 1973 by Ralf Bohle, with roots in the family business founded in Bergneustadt in 1922. Today it is based in Reichshof and makes bicycle tyres and inner tubes. Its name means “swallow” in German and translates Swallow, the name of the first tyres imported from Korea.
