Thanks to the lightweight aluminum valve and butyl rubber construction, Zipp's Tangente Butyl Tube weighs only 89 grams. So it reduces that ever-critical rotational mass making your wheels lighter and your bicycle easier to pedal too. This fine tube is also made of .85mm-thick rubber for excellent reliability. The valve is 37mm long and features a removable core.
