Pirelli P Zero SmarTube RS

The SmarTube RS is significantly lighter and more compact than a standard butyl tube. By using advanced thermoplastic elastomer technology, it reduces rotational weight, which can improve your bike's acceleration and handling responsiveness.

This tube is compatible with tires ranging from 26 mm to 35 mm in width. Please check your tire sidewall to ensure your current setup falls within this range before purchasing.

Yes, this tube is suitable for use with rim brakes. However, because thermoplastic elastomer tubes are sensitive to heat, ensure your braking technique is consistent and avoid prolonged dragging on long descents.

Because the valve core is fixed, you cannot remove it to install a standard valve extender. If your rims require a longer valve length than the provided 42 mm, you will need to use an external slip-on style extender.

While the SmarTube RS is optimized for high-performance racing, it is durable enough for regular training if you are careful during installation. Its primary benefit is weight reduction, so it is an excellent choice if you want to make your bike feel snappier on every ride.

Installation is similar to a standard tube, but you must be extra careful not to pinch the material between the tire bead and the rim. We recommend slightly inflating the tube just enough to give it shape before seating it inside the tire to prevent twists or folds.
