Specialized Airlock Schrader Valve Tube

Unlike traditional liquid sealants that can pool at the bottom of the tube and cause an unbalanced ride, the Airlock formula is homogenous. This means the sealant is evenly distributed throughout the rubber, ensuring a smooth, consistent rotation while you ride.

No, the Airlock formula is specifically engineered to be non-separating and non-toxic, which prevents it from drying out or clumping inside the tube. It remains effective for the lifespan of the tube, providing consistent puncture protection.

Yes, as long as your rim is drilled for a Schrader valve, this tube will fit. Just be sure to check that the valve length—either 32mm or 40mm—is compatible with your specific wheel depth.

While the Airlock sealant is excellent at sealing small punctures and slow leaks automatically, it is not a replacement for a patch kit. If you experience a larger tear or puncture that the sealant cannot close, you can still patch the tube as you would a standard one.

Because the sealant is integrated into the rubber compound rather than being a loose, watery liquid, it is significantly cleaner to handle than traditional tubeless sealants. You won't have to worry about liquid spilling out during a roadside tube change.
