Continental inner tubes are constucted via their own Unitube system, the advantages of this system are as follows:

- Multi-size tubes allow greater compatibility with more tyre sizes, & fewer tubes.
- All tubes are seamless & mold-cured (vulcanized) to ensure uniform roundness & improved reliability at the valve stem.
- Each & every tube passes a stringent 100% quality control inspection.
- Valve Length: 34mm
- Weight: 138g
