The most advanced road cycling inner tube in Pirelli’s range: lighter, more compact and stronger than any of Pirelli’s butyl tubes. P ZERO™ SmarTUBE was designed to match the need for lightness and handling of professional World Tour riders and its first application was inside the P ZERO™ Race Tub SL. It is now also available for every amateur cyclist. 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 twice as resistant against punctures as an equivalent tube made of butyl. P ZERO™ SmarTUBE is the ultimate evolution for cyclists who 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 tyres. Features Valve Length: 60mm. Valve: Presta. Compatible with disc and rim brakes. Weight: 700x23/32c - 35g, 700x28/35c - 70g.
