Quality innertubes pre-filled with our Dr Sludge solution - In the event of a puncture, the liquid rubber 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. Now pre-filled into inner tubes in the correct dosage. Prevents flat tyres Seals punctures instantly up to 3mm diameter Works time after time Water based with anti-corrosion properties and is completely harmless Inner tube and tyre will not stick together Will not dry out regardless of outside temperatures Every inner tube is individually tested before leaving the factory

Not all that.
These are a nightmare to get air into. The anti puncture sludge gets into the valve. Plus a few days after fitting I found out they are not puncture resistant.

Not the inner tubes that I thought I ordered
The inner tubes were the wrong size valves, would like to exchange inner tubes for the 40 mm valves but haven’t had any look as yet

More time riding than fixing
