The Pirelli Scorpion SmarTube is a mountain bike-specific inner tube that utilizes advanced Thermoplastic Polyurethane (TPU). This material provides an ideal balance of puncture protection, minimal weight, and reduced volume compared to traditional butyl. Weighing only 95g, it is a high-performance solution for marathon racers and trail riders seeking a reliable, high-strength tube.

The compact design allows the SmarTube to take up to 50% less space, making it the ultimate spare for on-trail storage. Featuring a 42mm Presta valve with a removable core, it is designed specifically for 27.5-inch tires between 2.2 and 2.6 inches. This lightweight and resistant tube is built for the rigors of enduro and off-road riding where every gram counts.
