I dont ride on surfaces or hard enough that I am almost breaking rims, so I've never really looked into a liner.

I thought these were out for about 2 years. We have a customer that loves them, but they ARE A PAIN to install...

I don't get it. Doesn't the sealant just soak into it?

It's a foam (or foam like) tire insert that let's you run even lower pressures, while adding extra protection to the rim from hard impacts, and the tire from pinch flats. They have been around for awhile now on MTBs, and are now trickling into gravel bikes as well.

yes, I understand that. How does it interact with sealant?

The video says its eva foam and doesn't absorb sealant.
There is a special valve to use too since the typical tubeless valve would just push air into the bottom of the foam liner which would make for slow inflation.
I guess it could be useful if you ride on some aggressive singletrack.
Seems overkill for gravel roads.

The foam seems kind of heavy. I bet if someone made tire inserts that were bladders of butyl rubber filled with air, they'd sell a million of them.

At $30 compared to Cushcore inserts ($150!), they’re a bargain. I’d definitely try them since my wheels were expensive and I don’t have options for smooth gravel roads here (near Kern River in Bakersfield).

Didn't a pro team experiment with some foam inserts inside tubeless tires on a few stages at this year's Tour de France?
I think the goal there was to keep the tire seated on the rim if it flatted, so that riders could make a quicker change.

Some “gravel” can get quite choppy, especially at speed. Also, part of the idea here is that you will run lower pressures than if you didn’t have them, getting the benefit of lower pressures and stronger damping without risking pinch flats or burping. I haven’t used tire inserts myself, but it’s a proven concept for off-road riding and it makes sense. As previously noted, it’s even being experimented with by professional road teams that use tubeless tires. I don’t think it’s going to be a super mainstream item, with everyone running tire inserts for gravel riding, but it’s going to be a nice option for those who would benefit from it.

I haven't had any issues just running tubeless, but a friend has been using the cushcore inserts and loves them. He runs 25psi with no issues and said it helped on the really chunky descents.

You can drop your pressure unbelievably low without pinch flatting, burping. For some these are worth giving a try, but again. they are a PAIN to install...

It not a bad idea, and at $60 for a pair (with valves) the price isn’t crazy. I would almost buy it just to see what it is like to run narrower tires again but with ridiculously low psi.
