The Schwalbe AV9 inner tube replaces the tube inside a 24 inch wheel when the tyre is punctured or worn. The model covers tyres from 1.10 to 1.75 inches, corresponding to ETRTO size 28/47-507/541, and has a 40 mm AV (Auto/Schrader) valve. Before buying, check that your tyre width falls within this range.
The inner tube is made of butyl and weighs 130 g. To choose, read the size printed on the tyre sidewall and compare it with the technical data: if it falls within the range 24 inches × 1.10–1.75, this is the version to choose.
