Pirelli PZero SmarTube

The SmarTube is made from polyurethane rather than traditional butyl rubber. This material allows it to be significantly lighter—weighing just 35 grams—while offering double the puncture resistance of a standard tube.

It is designed for 700c wheels with tire widths ranging from 23mm to 32mm. Please check your tire sidewall to ensure your current setup falls within this range before purchasing.

The valve length you need depends on the depth of your wheel rims. You should choose the 60mm valve for standard shallow rims and the 80mm valve if you are using deeper aero rims to ensure you have enough clearance to attach your pump.

Yes, its compact design makes it an excellent spare. Because it packs down much smaller than a butyl tube, it takes up significantly less space in your saddlebag or jersey pocket.

Installation is similar to a standard tube, but you should be careful not to pinch the material during the process. It is always a good practice to lightly inflate the tube before placing it inside the tire to help it seat properly.
