Many times I wonder if this thread should be changed to “Ask Dee Hubbs”

Dee Hubbs has actual information. I mostly bring opinionated bloviation that has a vague relation to reality.

And this is why I respect you.

I’d give Dee props but his opinions on sock height continue to be disturbingly incorrect.

[XXX-er]

you want your sock color to match you bike

Yea, him too, even if it is opinion it almost always useful and relevant.

Is there a good way to tell just looking if a used bike my buddy bought was set up tubeless? It's not so old that everything isn't tubeless ready, but it's certainly old enough that the sealant would have dried up and not be weeping through anywhere. Is there a smell test?

[rudy]

Push the valve core through?

[rudy]

Then smell. Obviously

[Dee Hubbs]

First test, is the valve core removable? No = tube
Remove or loosen the valve lock ring and push the valve into the rim. If it hisses air it’s Tubeless.

I think >75% of my tubes in the past 15 years have had removable cores so I think test one is only a pretty quick rough elimination test. And I always just bought whatever tube was the cheapest, I wasn’t seeking them out.

Even if it passes, there’s a pretty good chance it could still be a tube.

[Andeh]

Yeah, I was going to say, several years ago I bought a complete bike that supposedly was going to come set up tubeless. I pulled the valve cores out, squirted sealant in, then at some point later when changing tires realized I'd filled tubes with sealant.

[stuckathuntermtn]

Ok, thanks. Will it seal again if there's no sealant, though?
