Keep your bike rolling with confidence using the Schwalbe SV7 inner tubes. Designed to suit a wide range of 20 inch tyres, these high quality butyl inner tubes help cyclists spend less time topping up tyre pressure and more time enjoying their cycling, whether commuting, cruising bike paths or exploring local trails.

If you’re looking for a reliable replacement tube that holds air exceptionally well, the Schwalbe SV7 is a proven choice. Its wide size compatibility makes it ideal for many 20 inch bikes, while Schwalbe’s strict manufacturing process helps deliver consistent performance every time you head out.

Excellent air retention

One of the biggest advantages of the Schwalbe SV7 is its outstanding ability to retain air pressure. Each tube is manufactured from high quality butyl rubber and individually moulded to achieve an even wall thickness, helping reduce pressure loss between rides and making regular maintenance less frequent.

Factory tested for dependable performance

Every Schwalbe SV7 inner tube is inflated and stored under pressure for 24 hours during production to verify air retention before leaving the factory. This additional quality control provides confidence that you’re fitting a tube built to Schwalbe’s exacting standards.

Covers a wide range of 20 inch tyres

Thanks to Schwalbe’s Group Tube System, the SV7 is designed with excellent elasticity to fit a broad range of tyre widths. Whether your bike uses narrower 20 x 1.50 tyres or wider 20 x 2.40 tyres, a single tube model covers multiple popular sizes.

Ideal for everyday cycling

Whether you’re replacing a punctured tube, carrying a spare or refreshing an older bike, these tubes are well suited to commuters, recreational cyclists, folding bikes, BMX-style bikes with compatible wheel sizes and many children’s bikes using 20 inch wheels. Long lasting air retention means less time with the pump and more time enjoying your next ride.
