PirelliP Zero SmarTUBE 700c Road Tube(Return to Product Page)

just installed this on the rear tire after a flat, and road 16 miles. I ride 28 mm wide tires that don't tend to flat much (knock on wood) so I'm eager to see how resistant the TPU tubes are to punctures and such. will update in a few months after riding a few hundred miles.

Installation wasn't much different than a traditional tube, although I found I needed to inflate a bit more than the recommendation loading pressure in order to get the tub to sit properly in the inside of the tire.

One minor annoyance - the tube doesn't come out of the box in the next roll as pictured; instead it's wrapped around a useless piece of cardstock, which means if you plan to keep in your saddle bag you'll want to unwrap it, recycle the paper and then re-wrap.

Nothing really to say, which is a good thing. No issues with install. No flats yet with GP5000. So pretty good for a light weight tube! Big plus is that air doesn't leak down like latex. Recommended.

This is the best way to shed weight without the maintenance of tubeless. Size and weight are awesome. Been riding for months with no issues/flats and they hold air longer that butyl. Highly recommended, it’s a no brainer, reducing rotational mass, especially if you run 25mm tires or larger!

With cost of latex tubes & a major manufacturing flaw no one wants to challenge due to stem seating in tube , hoping so far that this technology will answer the ???.
