Quality inner tubes pre-filled with our Dr Sludge solution in the correct dosage. In the event of a puncture, the solution is forced to the hole by centrifugal force and on contact with the air, seals it immediately and permanently with minimal loss of pressure.

> Works time after time
> Water-based with anti-corrosion properties and is completely harmless
> Inner tube and tyre will not stick together
