Pirelli P Zero SmarTube RS Tube

The thermoplastic elastomer material used in this tube is sensitive to the heat generated by rim brakes. Using it with rim brakes can lead to failure, so it is strictly engineered for use with disc brake wheelsets only.

At just 34 grams, the SmarTube RS is significantly lighter than a standard butyl rubber tube, which typically weighs between 100 and 150 grams. This reduction in rotational mass can noticeably improve your bike's acceleration and handling.

This tube is designed for tires with a width between 26mm and 35mm. Please check your tire sidewall to confirm your current width falls within this range before purchasing.

No, the valve core on this tube is fixed. If you use valve extenders, you will need to use a type that threads over the existing valve rather than replacing the core.

Because of the thermoplastic material, this tube folds down to a much smaller size than traditional rubber tubes. It takes up very little space in a jersey pocket or saddle bag, making it an excellent choice for a lightweight emergency spare.

Installation is similar to a standard tube, but you should be extra careful not to pinch the material during mounting. We recommend using a small amount of air to give the tube shape before inserting it into the tire to help prevent twists or folds.
