Schwalbe Inner Tube - No. 4 | 16"/18" - 28/37-340/355 | AV 40mm

Schwalbe Standard – The Safe Choice

The advantages of the Schwalbe standard inner tube:

• High air density and elasticity
• High load capacity, puncture resistance, and riding comfort

Reliability. Schwalbe inner tubes are known for their high reliability. Each inner tube is inflated for 24 hours at the factory and checked for air retention.

Tightness. Schwalbe pays close attention to material purity when manufacturing its butyl inner tubes. The result is inner tubes that hold air pressure significantly longer than comparable models.

Systematic. Schwalbe bicycle tubes are particularly elastic and usually fit several tire sizes. That is why the manufacturer refers to them as a group tube system.

Recyclable. Schwalbe inner tubes are 100% recyclable. Each new butyl inner tube consists of around 20% recycled old inner tube.
