Product ID: 1005181

The Presta valve S-Tubo is Tubolito's top-end MTB Inner Tube offering and is designed to fit 1.8-2.4 inch tyres.

Incredibly light and fast-rolling thanks to the TPU (Thermoplastic Polyurethane Elastomer) construction, this tube has been designed primarily for performance, yet retains the puncture resistance of a butyl tube.

Tubolito S-Tubo MTB Inner Tube 1.8-2.4" Presta

Designed to provide the lightweight performance benefits of latex, but the puncture resistance of butyl, the Tubolito S-Tubo MTB Inner Tube is game-changing in its performance. Suited to 1.8-2.4 inch tyre widths and with a 42mm Presta valve, this tube matches latex in its weight and rolling resistance, providing incredible weight savings of 80% compared to a standard butyl tube. This is down to the unique TPU (Thermoplastic Polyurethane Elastomer) construction, combining the properties of a rigid thermoplastic with a soft elastomer.

Seams are reduced to add robustness and the tube ages well. The size was also another consideration in the design, and the S-Tubo packs down small to fit in a saddlebag or jersey pocket.


  • Manufactured in Europe
  • Tyre width compatibility: 1.8-2.4 inch
  • Optimised for low weight and lowest rolling resistance (matches rolling of latex tubes)
  • Similar puncture resistance to butyl tubes
  • TPU (Thermoplastic Polyurethane Elastomer) combines a hard, rigid thermoplastic with a soft and elastic elastomer and reduces the rotating mass
  • Compact size for convenient storage
  • Reduction of seams to a minimum to ensure maximum robustness
  • Very good aging and abrasion behaviour
  • Easily patchable with Tubo-Flix-Kit
  • A wheel with an S-Tubo-Road instead of a standard butyl rubber tube will accelerate to a 4% higher top speed (lower rotating mass)
  • Lightest and smallest bicycle inner tube in the world
  • Valve length: 42mm
  • Weight: 44 grams (27.5 inch) / 45 grams (29 inch)
  • Weight saving (over a standard butyl tube): 80% (27.5 inch) / 80% (29 inch)
