PirelliP Zero™ SmarTUBE 23/32-622 700C Presta 60mm Single Pack - Enhanced Cycling Experience, Lightweight Design, Speed Boost, Customized Fit

So far so good. Nice light weight option. I have only put around 100 miles on them so far, but no complaints. I don’t actually notice a big difference in ride quality except I think they roll a little faster than the old standard butyl tube. I have tubeless too, it’s just a lot of maintenance. This seems like a nice alternative.

These are fantastic ! Unlike butal tires that looses 20 psi every 24 hours. These just dont lose ANY AIR ! UTTERLY FANTASIC!.Now, I see people having trouble installing these. Well I come from a butal tube background that is slippery as all get out so I've learned how to install butal tubes and these aren't any differant. I DO NOT partially inflate. That my friends is bad advice. I also use corn starch to install tubes AND TIRES. They just slip on, well most of the time. DON'T INFLATE AND DON'T TWIST THE TUBES. For goodness sakes put the wheel on ur lap and install the tube & tire the easy way. And don't forget the corn starch. I actually have a dry paint brush that I use to "paint" the corn starch on the inside of the tire and I put corn starch in a zip lock bag and put the tubes inside and shake the heck out of it until the tube is coated with corn starch. Then and only then do I start my tire install. It usually slips on without any tools. WITHOUT ANY TOOLS!when I carry spare tubes with me on my rides they are wrapped in thier own corn starched zip lock bags ready to do their job when the time comes. Take ur time and do it right. It's a sucky job and u don't want to do it twice, or 3x if u really scew up (if u dont check the inside of the tire 4 sharp objects).Do this for yourself and avoid the aggravation when a flat takes place.USE CORN STARCH !I will buy more of these particularly for the rear wheel because these are almost 2 oz lighter. Less weight easier to turn over.One more thing, I use these on rim brake wheels without any problem. I know some poly tubes will melt if used on rim brakes due to excessive heat. but these tubes seems to handle warm to hot rims during excessive braking. I've use them I trust them I will buy more Pirelli tubes.

While I like the weight and the tube itself, the stem is too small and rubs on the frame side of the stem hole. The stem itself is a cheap rubber. The result was a leak in the stem itself after only a few hours of riding.

These tubes were easy to install and looks great. My old tubes were 99g and these are 35g. Thanks for a great product.

I run my tires at about 80psi, and these hold air roughly twice as long as the other butyl tubes I've used. Given the time between punctures I'm willing to state that these are probably more puncture-resistant as well. The only punctures I've encountered with these tubes are a furniture staple (and nothing's surviving that), and a puncture so small that it wasn't visible even after I discovered where the air was escaping from. In both instances I did not notice I had a puncture until the following day since the punctures were small and didn't rip at all.Not sure how people are having difficulty installing these. They work the exact same as any other tube and you would have to be incredibly careless to wreck them on installation.My only complaint is the plastic valve stem material. A lot of people put electrical tape over the valve stems when they have carbon wheels to prevent rattling. If they had a rubberized or fiber coating (like modern automotive wheel well inserts) it would eliminate the need to do that and I would give it a 5 star rating.

Installed in my 26 mm wide road bike tires. I found them easier to work with than butyl tubes. They retain air pressure much better than either the butyl or latex tubes I've used. Their ride and performance is great, but one tube (rear wheel) developed a tiny pinhole leak after just a couple rides. I successfully patched the leak with the Pirelli TPU specific patch kit. Then, after another 500 mi or so, the same tube developed another leak in a different place (the patch held fine). The leaks were on the side of the tube in contact with the tire, but I could not find anything in the tire casing that would have punctured the tube. Both leaks were super tiny - I could only find them by dunking the inflated tube in a bucket of water. Both leaks resulted in a complete loss of tire pressure an just a few minutes. Verdict: light, but does not inspire a lot of confidence.

The installation process was easy enough. The bright yellow color makes it easy to see danger of getting caught between the bead of the tire and rim.I am not sure about performance as my rides have been on rough chip seal. I will know more when I get to ride on some "road candy," smooth asphalt.These tubes are lighter than latex but may not be as lively, as the material doesn't seem as supple. That would affect ride performance but also makes installing easier.

You feel it on the bike!! WaW
