The Scorpion SmarTUBE Lite is Pirelli's ultralight TPU inner tube for modern off-road riding, from XC to enduro. It cuts rotating weight for sharper acceleration and packs down small enough to be the spare you always carry.

Highlights

• 43g claimed, 55% lighter than the standard Scorpion SmarTUBE
• 52% thinner and very compact as a spare
• 6.4% lower rolling resistance (Pirelli figure)
• Fits 29in and 27.5in tyres from 2.0 to 2.6in
• 42mm black Presta valve

Lighter, faster

Compared with the standard Scorpion SmarTUBE, the Lite is 55% lighter and 52% thinner, reducing rotating mass for better acceleration and responsiveness. Pirelli measures a 6.4% reduction in rolling resistance, so you use less energy holding speed on long trail rides.

Upgrade or spare

Use it as a performance upgrade for a tubed set-up, or carry it as a compact spare on a tubeless bike.

Compatibility & fit

Fits 29in (622) and 27.5in (584) tyres from 47 to 65mm wide (2.0 to 2.6in). Disc brake wheels only: not for rim brakes. The 42mm Presta valve needs a rim with a shallow enough valve bed; check your rim depth. Tube fitting is available as a separate workshop service; it is not included in the price.
