Why We Like The S-Tubo MTB Tube

The Tubolito S-Tubo MTB Tube is designed to have the lowest weight and smallest pack size possible. This makes it ideal to use as a spare tire in our trail repair kit.

  • Measures only 1.4 x 2in with the valve stem removed
  • Offers the same puncture resistance as standard rubber tubes
  • Fits 29in tires ranging from 1.8 - 2.5in wide
