A Compact, Lightweight Tube Designed For MTBs

The Scorpion SmarTUBE is a mountain bike-specific inner tube that blends the innovative features of TPU (Thermoplastic Polyurethane) — a specific formulation for the riders looking for the best balance between puncture protection, weight, and volume.

The SmarTUBE is a one-of-a-kind inner tube: low weight and volume are combined with a high level of reliability. These qualities are not present in an equivalent butyl tube.

It is the perfect solution for marathon racers and trail riders who are looking for a lightweight, resistant, and compact spare tube.


  • The folded-up volume of the SmarTUBE is up to 50% less than an equivalent butyl tube
  • Made of TPU (Thermoplastic Polyurethane)
  • Easily stored in a back pocket or strapped to the frame
  • Availiable in 27.5" & 29" wheel sizes
  • Weights: 75g for the 29" & 95g for the 27.5"
  • Not compatible with rim brakes
