3T had a sweet booth at Land Run 100. Then, I found these on sale stupid cheap ($360) at chainreactioncycles.com.
I popped a 28mm Clément Strada LGG on one and it instantly plumped out to 31mm @ 100 psi. 1800’ish grams. I think the wheels will support tubeless, although they don’t appear to be specifically tubeless compatible.
