Zipp Tubes 700 x 23c

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 aluminium 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 aluminium 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
