There will be no unboxing in this review, nor a detailed explanation of Thermoplastic Polyurethane (TPU) because I couldn’t if I tried, but I have one important thing to say about these 35gr inner tubes – they work!
Contrast this with a long string of failures with the same type of super-lightweight tubes from Tubolito (in their defense, others I’ve talked to haven’t had the same issues) and I can say I’m a fan of Pirelli. Not only are they stupidly light, I can leave the bike for a week and lose only 10psi. And yellow is cool, even if you only get to see it when you install them.

Gerry. Sold. I loved my Tubolitos on the C64 for about two months. Then they failed, and then they failed, and then they failed……and then I gave up. I’m happy to try these with your endorsement. I’ll give you a report in October. Thanks.
I’m sorry to hear about your Tubolito woes, Eric. I hope that wasn’t a recommendation from me!
Pffft. Who even uses tubes these days…? 😝😉😂
(Also, I just Googled the Pirelli P Zero SmarTUBE, they cost HOW MUCH?!?!?!)
This is one for the weight weenies, no question. It is actually on the cheaper side of things when you consider weight vs $$$, but yes, not cheap!
Leave the bike for a week !???!
Good point, Sam. The bike is rarely unused for that long!
Thanks for the review – I’m looking for a super-compact/light tube as a back-up for the saddle-bag, does anyone have any feedback on how these survive as ‘unused’ spares? that seemed to be a failing of the Turbolito’s, they couldn’t be relied on to work in an emergency, as would degrade / be too fragile… Anyone got any feedback? 🙂
It’s a good question and one that I’m glad I haven’t tested out yet! I didn’t really know that about Tubolitos, although I’m not surprised. So far the Pirellis have been golden. They still hardly lose any air, even after a few days.
