You can choose between two different inner tubes.
CST Inner Tube
All our models are equipped with high-quality butyl inner tubes from CST. The CST tube holds the pressure longer, in comparison with most other inner tubes. Car/Schraeder valve.
Schwalbe Inner Tube (Not available in all regions)
A tube is not just a tube. Schwalbe tubes retain the pressure longer than all other tubes, thanks to their rubber mixture and material purity. Schwalbe tubes are the only tubes that carry the sought after “VSF-All Ride” seal of approval. Car-/Schraeder valve.
