Pirelli P Zero™ Smartube Evo Presta 42 Mm Inner Tube

The P ZERO™ SmarTUBE EVO is Pirelli's latest innovation in the world of tubes, as we strive to improve performance in modern cycling. They are the result of our development for World Tour tubulars, now made available for everyday rides with clinchers. Made of thermoplastic polyurethane (TPU), it can save up to 70% of the weight of ordinary butyl tubing and nearly 50% of pocket space, while being stronger than butyl as a raw material.
