Has anyone taken an unknown brand hooked carbon wheel that didn't have markings for being tubeless ready & make it tubeless ready?
I'm thinking that if tubeless tape is used, it would be capable but I'm not sure what makes a carbon wheel different in that aspect.

I could buy the rim tape, sealant, TLR Tire, & try it, but would like to not overlook something that others would know.

It's double walled, but I haven't seen any not double walled.

Does each wheel have at least one drain or vent hole?

Troul 

no drain or weep holes.

Then there is a potential risk that, if the rim bed is not perfectly sealed, you may end up pressuring the internal void of the wheel, which may result in a CF assplosion.

A bigger concern for me is "unknown brand." Could be great, could be a cheap knock-off.

It is my understanding that tubeless tires run at lower pressures, so that might help. But not my area, so good luck.

the better reputable build set I have dont have the holes. both of the rims almost could pass as twins.

1. Is "the better reputable build set" a tubeless wheelset?
2. With so open mold wheelsets available, there is no basis to assume that the construction of the two wheelsets are same or equivalent.

Heck, just get out your drill and a tiny bit and make your own weep hole (sounds so wrong). 💀

Seems like a good way to end up with you teeth in the asphalt.

1. yea
2. that makes more the reason to have a distinguishing difference made into the designs.

Troul 

wasn't aware that wheels could punch like that. I'll not be buying those.

Does the prospect rim have a shelf between the bead seats? If so, then the answer is a 100% maybe. The shelf is necessary so the bead has something to come up and rest upon. Else the risk of a burp and related complete and unscheduled demount from the rim is much more likely.

Troul 

by shelf, are you referring to the aforementioned "hooked" or something entirely different?

SoSmellyAir

No. base2 is referring to the shoulders on both sides of the rim bed. See, e.g.:

AR46 Carbon Road/CX/Gravel Wheelset - Light Bicycle

Both hooked and hookless tubeless wheels have bead shelfs / shoulders.

Better check that you have that better reputable build set up correctly then.

Troul 

the spoke valley is present within it.

Troul 

no reason to second guess the better reputable build.

surak

Except the reason is plain if you bothered to read the thread. My mistake for thinking that you posted because you wanted to understand the safety aspects of your wheels.

Troul 

I want to know what makes a carbon wheel tubeless vs not.

Koyote

That reminds me: on one of my reputable rims (Roval) I started seeing sealant weeping from that little hole on the sidewall...I hadn't known what that hole was for until then. Replaced the old valve with a fresh one and all was good.

Kontact 

Having you tires blow off thee bead is extremely dangerous. Much more so on road bikes. You don't know if this is tubeless compatible

Troul 

tubeless tends to lower PSI required, & if anything, I'd expect a slow leak or sealant spewing after setting it up.
I'm looking for responses that will give key indicators that determine what makes a carbon rim being tubeless compatible.

SoSmellyAir

This response does not clarify whether there are bead shelves within the wheel.
