Pirelli P Zero SmarTube RS Tube - 700c x 26–35mm, Presta, 80mm Valve, Thermoplastic Elastomer
The Pirelli P Zero SmarTube RS is built for riders who care about speed, weight savings, and rolling efficiency without committing to a full tubeless road setup. This is not a standard butyl tube—it uses advanced thermoplastic elastomer construction to dramatically reduce rotational weight and rolling resistance.
Compared to the standard SmarTube, the RS version is even faster, offering up to 1.5 watts more efficiency by reducing rolling resistance and improving responsiveness under load. For performance road riders, that matters.
This is the upgrade for riders chasing speed with deep carbon wheels, race bikes, and high-performance endurance builds where every gram and every watt count.

Compatibility & Technical Notes
Good Fit: high-performance road bikes, endurance bikes, race bikes, deep carbon wheel builds, and riders using 26–35mm road tires.
Not A Fit: standard Schrader valve wheels, MTB setups, gravel tires wider than 35mm, or riders wanting maximum puncture protection over outright speed.
The 80mm valve length is specifically useful for deeper carbon rims. Always confirm valve length against rim depth before ordering.
Service / Ownership Context
These tubes ride differently than standard butyl tubes—faster acceleration, lighter steering feel, and better road response. Riders often notice it immediately on lighter carbon road bikes.
They are lighter and faster, but also require more careful installation. Pinching these during install is a common mistake because they are thinner and more delicate than standard tubes.
Fit & Use Signals
Best for:
- Road race bikes
- Performance endurance bikes
- Lightweight carbon wheel builds
- Riders avoiding tubeless sealant maintenance
- Fast training and race setups
Not ideal for:
- Heavy commuter use
- Maximum puncture protection priorities
- Hybrid bikes with Schrader valves
- Wide gravel setups over 35mm
