BBB 20-Inch Presta Innertube

BBB innertubes are made of durable long-lasting butyl rubber compound. Seamless to prevent the innertubes from leaking air and keep air pressure for a long time. Air chamber wall-thickness of 0.87mm. Thick enough for extra puncture resistance and thin enough to spare you the extra weight.

This French valve type was originally used for road bikes.
