Schwalbe AV13F Freeride Inner Tube

The Schwalbe AV13F Freeride inner tube is designed for 26-inch mountain bike wheels with freeride tyres, in ETRTO size 54/75-559. It has a AV (Autoventil) valve measuring 40 mm in length, which should be checked against your rim before purchasing.

There are no variants to choose from: only the size matters. Check the actual tyre width and make sure it falls within the manufacturer's stated 54-75 mm range before fitting the inner tube. The ETRTO size is the first specification to check, and with a AV valve it is also worth checking that your pump is compatible with this valve type.

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.
