The Airlock Presta Valve Tubes are among our top picks for performance tubes because they are lined with tire sealant to prevent leaking air from punctures. Specialized uses a non-separating sealant formula to prevent sealant from pooling in your tire or tube, for a smooth, even-rolling experience.
