Not black, but bright yellow + magical material: the Pirelli tube
Tubolito marked the starting point, Schwalbe recently followed suit with the Aerothan tube, and now Pirelli is modernizing the tube for bicycles. Thermoplastic polyurethane, TPU for short, is the magic material that makes inner tubes around three to four times lighter than their butyl counterparts. In addition, the TPU inner tube takes up to 50% less volume, which is ideal for storing it in a rucksack or jersey to save space.
In addition to road versions, the Pirelli Smartube made of TPU is available in the dimensions 27.5x2.2-2.6", 29x1.8-2.2" and 29x2.2-2.6", all with a 42 millimeter Presta valve. The tubes are expected to be available from specialist retailers from August.velo.pirelli.comFurther content on this article
