Specialized isn't afraid to say it - their Airlock Presta Valve Tubes are the best-performing, self-sealing bicycle tubes available.

That's because they feature our powerful Airlock sealant that coats the tube for permanent protection against punctures. Not only this but the sealant is designed to work continuously in order to prevent slow leaks from occurring, so erring complete catastrophe, you won't have to worry about flatting when you're riding over debris. Specialized even addressed the common issue of sealant pooling with a completely homogenous design, so the tire/tube combo will always roll smoothly and even.


  • Airlock inner tube sealant for the best chance of reducing punctures.
  • Non-toxic, non-separating formula.
  • Works continuously to prevent slow leaks.
  • Homogenous design prevents puddles with no need to shake.
  • Will not dry out like the many other sealants.
