Inner Tube | Pirelli SmarTube X

Stronger. More compact. And built to withstand tough gravel rides.

The Cinturato SmarTUBE X is the heavy-duty version for those who want TPU, but with more robustness for challenging gravel. It is made of thermoplastic polyurethane (TPU), and is designed to be more compact than a conventional inner tube, while drastically reducing weight compared to butyl.

It is also 3× thicker than a standard SmarTUBE: this means more material, more strength, more peace of mind when the terrain gets rough and you are far from your starting point.

Please note: it is not designed to be repaired, and must not be used with rim brakes.

In short: a TPU "adventure/gravel" tube, made to last, not to mess around.
