Specialized Airlock Presta Valve Self-Sealing Bicycle Tube

Self-Sealing | Presta Valve | Airlock Sealant | Multiple Sizes

The Specialized Airlock Presta Valve Tube is engineered to help keep you riding longer with fewer flats. Filled with Specialized's exclusive Airlock self-sealing sealant, these premium inner tubes automatically seal small punctures while continuously helping prevent slow air leaks.

Unlike many self-sealing tubes, Airlock features a homogenous, non-separating formula that stays evenly distributed inside the tube, eliminating sealant pooling while providing smooth, balanced performance throughout every ride.

Ideal for road, gravel, mountain, and hybrid bikes, Airlock tubes deliver dependable puncture protection without sacrificing ride quality.


Integrated Airlock Self-Sealing Technology

The built-in Airlock sealant actively seals small punctures before they become ride-ending flats.

Benefits include:

  • Automatically seals small punctures
  • Helps reduce flats from thorns and road debris
  • Continuous protection while riding
  • Greater confidence on every ride

Perfect for riders who want dependable flat protection without switching to tubeless.


Continuous Leak Protection

Airlock doesn't stop working after installation.

The advanced sealant continuously helps prevent slow air leaks, allowing your tires to maintain pressure longer.

Advantages include:

  • Reduced pressure loss
  • Less frequent inflation
  • Improved reliability
  • More uninterrupted riding

Non-Toxic, Homogenous Formula

Unlike many traditional tube sealants, Specialized's Airlock formula remains evenly distributed throughout the tube.

Features include:

  • Non-toxic formulation
  • Non-separating design
  • No sealant pooling
  • No shaking required
  • Will not dry out like many conventional sealants

The result is smooth rolling performance and consistent puncture protection throughout the life of the tube.


Reliable Presta Valve

Each tube features a dependable Presta valve for lightweight performance and secure inflation.

Available with:

  • Standard Presta valve
  • 48mm Presta valve (700 x 20–28c)

Compatible with most modern road, gravel, cyclocross, hybrid, and mountain bike wheels.
