I've read a few older posts with fellow members who have sealed the spokes and used the TW31 tire.

How has it worked out for you? Can you run lower pressures?

Does it save any weight compared to using a tube?

Has anyone weighed the wheel before and after?

Thanks

comin from supermoto world I can say:
normally all the tires seals the rims on the shoulder, the problem is the spokes nipples, that you have to seal.
in total, is not a nightmare work, quite easy and the weight saving is exaclty the one of the tube

Thanks, I may try it out for myself.

I converted my rear TW wheel to tubeless w/ 3M 4200 Fast Cure & clear tape, running a Bridgestone TW204 street-biased tire - have not done the front conversion, yet. I do like it.

Seems to hold psi well - haven't gone below 15psi, but no reason to think it wouldn't hold it.
Flat/puncture repairs will be easier than having to remove the wheel, as with a tube.

Also, tubes are not only unsprung weight (bad), but are bound by the laws of rotational inertia:

When it's time to GO, the engine must work harder to put them into motion & when it's time to STOP, the brakes work harder to slow that extra rotating mass down, increasing braking distance & slowing brake response.

Do you recall which valve stem you used? Thanks.

Yep, EBay - as below. If I had to do it again, I’d choose a different one, though. This 90-deg fitting lays the valve stem so close to the wheel, some air chucks or pressure gauges will not fit it.

it would have been a hassle to return, or wait for a replacement, so I just installed it.

this is a junky but working solution, that come from the past, when everybody tried to eliminate the tube in the mountain bikes:
