Zipp Butyl Inner Tube 700c

The Zipp® Tangente butyl road inner tube with a removable core is designed to improve rotational stability by decreasing rotational mass at the valve body. It features a lightweight aluminum Presta-valve body, 37 mm length with a removable valve core.Tubes are 700c x 19-23 mm, weighing 89 g without a valve extender. The aluminum valve body saves weight, allowing us to make a tube that is .85 mm thick to optimize durability. Zipp Integrated Valve Extenders also are available in lengths for each Zipp wheel along with a handy wrench set. Note: Designed specifically for use with Zipp’s new Integrated Valve Extenders and Tangente Valve Wrench set.
