The Schwalbe SV13 Inner Tubes 2 Pack is a reliable choice for cyclists who want fewer interruptions from topping up tyre pressure and more time enjoying their cycling. Designed to suit a wide range of 26 inch mountain bike and hybrid bike tyres, these high quality butyl inner tubes help deliver consistent performance across everyday commuting, recreational cycling and trail use.

If you’re replacing worn tubes or keeping spares on hand, this twin pack offers excellent value and peace of mind. Schwalbe’s manufacturing process focuses on consistent wall thickness and outstanding air retention, making these tubes a favourite among cyclists who want dependable performance and less frequent inflation.

Excellent Air Retention

One of the biggest advantages of the Schwalbe SV13 is its ability to hold air pressure for longer than many standard inner tubes. This means less time reaching for the pump before every ride and more consistent tyre performance, whether you’re cycling to work, exploring local bike paths or heading onto your favourite trails.

Quality You Can Trust

Every Schwalbe tube is individually inflated before leaving the factory and checked under pressure for 24 hours. Combined with carefully controlled wall thickness, this quality control process helps ensure each tube delivers reliable performance from the moment it is installed.

Wide Tyre Compatibility

Thanks to Schwalbe’s Group Tube System and the elasticity of its premium butyl rubber, the SV13 fits a broad range of 26 inch tyre sizes from 1.50 through to 2.40 inches. That flexibility makes it an excellent replacement tube for many mountain bikes, hybrid bikes and recreational bicycles.

Convenient Twin Pack

Having a spare tube ready can turn an unexpected puncture into a quick repair. This pack includes two Schwalbe SV13 tubes, making it ideal for regular cyclists, households with multiple bikes or anyone who prefers to carry a spare on longer cycling adventures.
