PZero SmarTube - Presta Valve Poles and delivers 360 mg SodiumThe 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 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.
