Schwalbe SCV4 Inner Tube

The Schwalbe SCV4 inner tube is a standard replacement for 16 and 18 inch bicycle tyres, with an ETRTO size of 28/37-340/355. It has a 40 mm SCV valve, is made of butyl and weighs 85 g. It is compatible with ETRTO sizes 28→35-355, 28→37-349 and 37-340, covering several tyre sizes.

Start with the wheel size: the SCV4 is suitable for 16 or 18 inches, but always check the diameter written on your current tyre. If your tyre size matches one of the listed ETRTO sizes, the inner tube is suitable. Also check that the rim hole accepts the SCV valve before ordering.

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.
