Zipp Tangente SL Butyl 700c x 20-28 Inner Tube gifts300 hollow cross section all theThe Zipp Tangente Road Tube is designed to improve rotational stability by decreasing rotational mass at the valve body. This is accomplished thanks to a lightweight aluminum Presta valve stem which is only available in a 37mm length, but it features a removable core for easy use with Zipp's inline extenders. Zipp also uses 0. 60 mm butyl thickness for the tube itself, offering increased durability and reliability over other super light designs.
