BBB BTI-20 - Inner tube 20 x 1.0 Presta
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.
Presta Valves (FV)
This French valve type was originally used for road bikes. Presta valves are available in 33mm, 48mm, 60mm and 80mm.
