Scorpion™ SmarTUBE is the mountain bike specific inner tube that blends the innovative features of TPU (Thermoplastic Polyurethane), a specific formulation for the riders that are looking for the best balance between protection against punctures, weight and volume. Scorpion™ SmarTUBE is a one-of-a-kind inner tube: low weight and volume combine with a high level of reliability not available with an equivalent butyl tube. The perfect solution for marathon racers and trail and enduro riders that are looking for a lightweight, resistant and compact spare tube. Do not use with rim brakes.

The Scorpion™ SmarTUBE is chosen everyday by Pirelli PRO athletes as a spare tube thanks to its low weight and compactness, they can easily store it in the back pocket or strap it around the frame. No matter if racing or just training, you can always bring a Scorpion™ SmarTUBE along.
The replacement of butyl with TPU (Thermoplastic Polyurethane) gives the Scorpion™ SmarTUBE its unique features, a technical innovation that redefines the concept of inner tubes, both for everyday use and as a spare tube.

The volume of the Scorpion™ SmarTUBE is up to 50% less than an equivalent butyl tube making it the ultimate spare tube: it saves space and doesn't add weight on the trails.
