The P ZERO SmarTUBE is the most advanced inner tube in Pirelli's range. The standard butyl inner tube has been replaced with TPU (Thermoplastic Polyurethane), an advanced plastic m aterial 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. Show more
