The Tubolito Mountain Bike Inner Tube is a high-quality inner tube for 26-inch mountain bike tires. With a 1.8/2.5-559 size and a 42mm Presta valve, this inner tube is suitable for tire widths from 1.8 to 2.5 inches. What sets this inner tube apart is its robustness and puncture resistance. It is twice as robust as a standard rubber inner tube. Weighing only 78 grams, the Tubolito inner tube is also very lightweight and rolls up compactly. This makes it ideal as a spare tube for your mountain bike adventures. Note: If the Tubolito is not correctly assembled in the outer tire, the maximum pressure is 0.5 bar. This is because the material can deform plastically at higher pressures. The Tubolito inner tube is not suitable for rim brakes.
