Tubolito S-Tubo MTB Spare Tube

The Tubolito S-Tubo MTB inner tubes redefine lightweight and compact design. At just 44 grams, they're 80% lighter than standard tubes but match their puncture resistance. Made from thermoplastic, they shrink to 3.5 x 5 cm, fitting easily in pockets or packs. Ideal for emergency tubeless backup or weight-savers, they fit 27.5" and 29" wheels and 1.8-2.4" tires. They feature a removable 42mm Presta valve and include a valve tool, offering a light, small, and robust tube solution.
