P ZERO SmarTUBE RS

The Pirelli P ZERO SmarTUBE RS is built for riders who want the lightest, fastest inner tube possible for road racing. Using an advanced TPU construction, it delivers exceptionally low rolling resistance and a dramatic weight reduction compared to traditional butyl tubes.

• Up to 1.5 watts faster than the standard SmarTUBE thanks to reduced rolling resistance

• Ultra‑light TPU construction for maximum performance

• Compact design packs smaller than a traditional tube

• Presta valve available in multiple lengths (42 mm, 60 mm, 80 mm)

• Compatible with 700C wheels and 25–28C tires

• Weighs only 33 g (depending on valve length)

Ideal for competitive cyclists looking to minimize system weight, maximize speed, and carry a compact, high‑performance spare tube on race day.
