Borrowing the same tech as their XC version, the Vittoria Air-Liner Light Gravel tire insert weighs virtually nothing and uses a semi-permeable foam that expands if you puncture to fill the tire so you can keep rolling.

The material absorbs the air you inflate into the tire, slowly (over about 8 hours) equalizing the air pressure inside the foam’s air pockets and your tire. Then, if you puncture and the air rushes out of your tire, that pressure drop causes the air trapped inside the foam to expand and partially fill the tire.

Vittoria says it’s enough to let you keep riding…for a while, anyway. Unlike XC, where it could be enough for you to finish a lap (or even a complete race), with gravel it could be enough to get you to the next aid station where you can perform a proper fix. Or, if you’re plugging the tire road side, it means you won’t have to mini-pump as much air back into it to get rolling again.

It also adds a quasi-suspension effect, helping support the tire at lower pressures and preventing pinch flats. I’ve been riding it on my XC bike and they’re nothing short of amazing – so much so that I gave them my Editor’s Choice award last year.

Maybe tell us one difference between the original version and the new Light version? Width, height, foam characteristics, etc? Anything that can be said beyond the press release?

Is that right? I’m pasting this line from vittoria.com.

“Suggested Tire Size 700×31/40mm”

Read again. That was the specs for the Air-Liner Gravel, and these are the new Air-Liner Light Gravel which Vittoria recommends 700c x 42-50 and the same for 650b.

Definitely expensive but you can use them for years and multiple tires

Tubeless inserts. The 27.5 of the tubeless world. Unnecessary, pita to install, sucks when you actually flat, and really doesn’t provide a true “ridable” (when flat) solution. PB had an interesting read where they asked all the top tire manufactures and DH riders about inserts. About 90% of them didn’t mess with them anymore, where a few years previous it was about 50%. I think most real world experiences with them are just not worth the price and install, and hassle if you get a flat.. Seems that trend has worn off except in fringe cases.

This is why I like the one that most people hate. The Huck Norris. It allows you to air down a little by providing protection from the hardest hits. It doesn’t make any crazy claims about damping and riding flat, and it is easy to deal with flats and during setup. I think it’s worth the money and effort for its simple benefits.
