Pirelli Scorpion Smartube Inner Tube 29x1.8/2.2 - 42mm

SmarTUBE is Pirelli's latest product in the world of inner tubes, developed to improve performance in modern cycling. These tubes are the result of the development made for World Tour tubulars, now made available for daily rides with clincher tires and inner tubes. Made from thermoplastic polyurethane (TPU), SmarTUBE can save up to 70% of the weight of a standard butyl tube and nearly 50% of the space in your pockets, while being more durable. They are available in a full range of sizes from road to MTB and include a reinforced version for Gravel or Endurance applications. These tubes have two major advantages over butyl versions: first, they reduce the rotating mass where it matters most, the wheels, making your bike more responsive and faster in accelerations and more manageable and smooth on climbs. Additionally, they save space in your pockets and bags, allowing you to carry more food and ride longer. Whether you choose them for weight savings or space savings, SmarTUBE tubes provide puncture resistance and high performance with style, also thanks to their Pirelli yellow color (Racing) – which never goes out of style.

Scorpion™ SmarTUBE is the mountain bike inner tube that leverages all the innovative features of TPU (thermoplastic polyurethane) with a design specifically for riders seeking the best balance of puncture resistance, weight, and volume.

Scorpion™ SmarTUBE is the perfect solution for cyclists tackling marathon, trail, or enduro routes who want the security of a lightweight, durable, and compact product to handle mechanical incidents.

Scorpion™ SmarTUBE is chosen every day by Pirelli PRO riders as a spare inner tube thanks to its reduced weight and volume; it can be easily stored in jersey pockets or attached to the frame. Whether in a race or training, you can always carry a Scorpion™ SmarTUBE with you.

Thermoplastic Polyurethane
Thermoplastic Polyurethane (TPU) is a next-generation plastic material, lighter and more durable than butyl, with better air retention than latex. It is available in glossy, bright Pirelli yellow for easy recognition. Thanks to TPU technology, you can save up to 70% of weight and up to 50% of space compared to a traditional inner tube.

Presta Valve
Pirelli SmarTUBE inner tubes are equipped with a standard Presta valve featuring an RVC glued core mechanism with a length of 42 mm to be compatible with most rims. The valve is black to give your bike a cleaner and more elegant look.
