Inner tube Angel™ SmarTUBE X

The Angel SmarTUBE X inner tube is made from thermoplastic polyurethane (TPU), which can save up to 70% of the weight of a standard butyl inner tube and almost 50% of the space in your pockets, while being stronger than butyl as a raw material.
The Angel SmarTUBE X inner tube is at least 3 times thicker than an ordinary SmarTUBE inner tube, giving you the advantage of being agile and rapide yet extremely protected, allowing you to cope with any type of obstacle on commuting trips or more occasional outings.

WEIGHT: from 145 to 183 g depending on size.
