Pirelli PZero SmarTube

Polyurethane is significantly lighter and more compact than traditional butyl rubber. While it offers superior puncture resistance and lower rolling resistance, it requires more care during installation to ensure it is seated correctly within the tire casing.

Yes, but with a caveat. Because polyurethane can be sensitive to the heat buildup generated by rim braking on long descents, these tubes are best suited for disc brake setups or riders who do not subject their rims to prolonged, heavy braking.

Your valve length depends on your rim depth. You need a valve that extends at least 15-20mm beyond the rim surface to comfortably attach a pump head. If you have deep-section aero wheels, you will likely need the 80mm option.

Standard rubber patches will not bond to this material. You must use a specific repair kit designed for thermoplastic polyurethane (TPU) tubes to ensure a proper, airtight seal.

Yes, the PZero SmarTube is compatible with tire widths ranging from 23mm to 32mm, making it a versatile choice for most modern road bike setups.

The material folds down to a fraction of the size of a standard butyl tube. This allows you to carry a spare in a smaller saddle bag or even a jersey pocket without it feeling bulky or cumbersome.
