Pirelli P Zero™ SmarTUBE, a lightweight inner tube for road bikes, is designed for those who want to reduce bike weight without sacrificing precise and responsive handling. Developed for use with traditional clincher tires and as a compact spare for tubeless-ready tires, this lightweight inner tube replaces classic butyl with a TPU (thermoplastic polyurethane) structure, an elastic and resistant material that allows for reduced bulk and significantly lower weight compared to a standard inner tube. The advantage is noticeable both on the bike, where every gram saved contributes to the overall responsiveness of the vehicle, and in a jersey pocket or saddlebag, thanks to its more compact and easy-to-carry format for training, long rides, or granfondos. The Pirelli P Zero™ SmarTUBE is suitable for cyclists looking for a technical solution to improve efficiency and practicality, maintaining compatibility with both disc and rim brake systems. The Presta valve completes a lightweight inner tube designed for road use, ideal for those who desire high performance, less bulk, and a reliable spare always on hand.
