Specialized Airlock Schrader Valve Self-Sealing Bicycle Tube
Self-Sealing | Schrader Valve | Airlock Sealant | Multiple Sizes
Ride with greater confidence using the Specialized Airlock Schrader Valve Tube, one of the most advanced self-sealing bicycle tubes available. Filled with Specialized's exclusive Airlock sealant, these tubes continuously seal small punctures and help prevent slow leaks, keeping you rolling through thorns, glass, and road debris without the hassle of frequent flats.
Unlike many self-sealing tubes, the Airlock features a homogenous, non-separating sealant that won't pool inside the tube, ensuring a smooth, balanced ride with no shaking required.
Self-Sealing Airlock Protection
The integrated Airlock sealant works continuously inside the tube to seal punctures as they occur.
Benefits include:
- Helps seal small punctures automatically
- Reduces flats caused by thorns and road debris
- Continues working throughout the life of the tube
- Provides added confidence on every ride
Ideal for commuters, recreational cyclists, and riders who want fewer interruptions.
Continuous Leak Protection
Airlock sealant doesn't just seal punctures—it also helps prevent slow air loss over time.
Advantages include:
- Reduces slow leaks
- Helps maintain tire pressure longer
- Less frequent inflation
- More dependable everyday performance
Non-Toxic, Non-Separating Formula
Specialized developed Airlock using a premium sealant formulation that remains evenly distributed throughout the tube.
Features include:
- Non-toxic formula
- Does not separate inside the tube
- No puddling or balancing issues
- No shaking required before installation
- Won't dry out like many conventional sealants
The result is smooth rolling performance with consistent puncture protection.
Reliable Schrader Valve
Each Airlock tube features a standard Schrader valve, making inflation simple with most bicycle and automotive air pumps.
Suitable for:
- Mountain bikes
- Hybrid bikes
- Cruiser bikes
- BMX bikes
- Comfort bikes
- Youth bicycles
(Valve length varies by size.)
