The smartube is pirelli’s latest product in the world of tubes as we continue to seek to improve performance in modern cycling. They are the result of our development for world tour tubulars now made available for everyday rides with clinchers. Made from a thermoplastic polyurethane (tpu) it can save up to 70% of the weight of a general butyl tube and almost 50% of the space in your pockets while being stronger than butyl as a raw material. They reduce the rotating mass where it counts the most (wheels) making your bike livelier and quicker in accelerations to help improve your handling and climbing speed. They save space in your pockets (or bags) so that you can carry more food and ride longer.
