P ZERO SmarTUBE is the most advanced inner tube in the Pirelli range. It was designed to meet the needs of professional World Tour riders for lightness and handling. The first application of this tube was inside the P ZERO Race Tub SL, and it is now also available for amateur cyclists.The standard butyl inner tube has been replaced with TPU (Thermoplastic Polyurethane), a sophisticated plastic material known for its elasticity and strength. As a result, the P ZERO SmarTUBE is up to 70% lighter and up to 50% more compact than a traditional butyl tube. It is also just as puncture-resistant.P ZERO SmarTUBE represents the ultimate evolution for cyclists who use the standard clincher setup and want to enhance their bike's performance. It is also a great option for those in need of a light and compact spare tube for tubeless-ready tyres.This inner tube is compatible with both disc and rim brakes, making it a versatile choice for riders.
