For cyclists who value performance and reliability, a thermoplastic polyurethane (TPU) inner tube is a convincing option. This innovative tube combines the advantages of traditional tube systems and tubeless tyres without having to accept their disadvantages.
TPU inner tubes offer a significant weight reduction compared to classic butyl inner tubes, which reduces the rotating mass and thus improves the riding experience. At the same time, they score with increased puncture protection and better riding characteristics, especially when cornering. They are easier to fit and require less maintenance than tubeless systems, which need to be serviced regularly.
TPU tubes are a worthwhile investment for amateur athletes looking for a reliable and low-maintenance solution, but also for professionals who want high performance. Despite higher purchase costs, the advantages outweigh the disadvantages, in particular the higher puncture resistance, lighter weight and improved riding characteristics.
Thermoplastic polyurethane (TPU) – the modern material in tube production offers a lot of advantages over butyl tubes:
weight savings of approx. 70 g per wheel
higher puncture protection
ultra-compact, therefore perfect as a replacement tube
less air loss
lower rolling resistance (at the level of latex tubes and tubeless systems)
easy assembly and repair
suitable for rim and disc brakes
TPU valve stem with bonded aluminium valve insert
- better hold of the valve
- less air loss compared to pure TPU valve stems
temperature stable in the range from -50° C to + 80° C
