Pirelli P ZERO SmarTube P ZERO SmarTUBE is the most advanced inner tube in the Pirelli range. 60mm valve length. The standard butyl inner tube has been replaced with TPU (Thermoplastic Polyurethane), an advanced plastic material characterized by elasticity and mechanical strength. The result is an inner tube that can be up to 70% lighter, up to 50% more compact and as resistant against punctures as an equivalent tube made of butyl. P ZERO™ SmarTUBE is the ultimate evolution for the cyclists that are still using the standard clincher setup and want to improve the performance of their bikes as well as those who are looking for a light and compact spare tube for tubeless-ready tires. The weight of the P ZERO™ SmarTUBE is a benefit. Compared to a an equivalent butyl inner tube, the P ZERO™ SmarTUBE can save up to 70% of weight. The replacement of butyl with TPU (Thermoplastic Polyurethane) gives the P ZERO™ SmarTUBE its unique features, a technical innovation that redefines the concept of inner tubes, both for everyday use and as a spare tube.
