Dr Sludge Self Sealing 12.5" Inner Tube

Valve

Dr Sludge Self Sealing Inner Tube (12.5 x 1.75-2.125): Dr Sludge is an invaluable puncture preventative for those who find themselves hampered by flat tyres. 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.
Benefits: Inner tube and tyre will not stick together, will not dry out regardless of outside temperature, every inner tube is individually tested before leaving the factory.
