I want to use my Belgiums, "Not +" as tubeless and I heard of people successfully doing it using Stan's no tubes.
Their conversion kit has a rubber rim tape with integrated valve but on some you tube videos I see people just using two layers of the yellow tabe with a tubeless compatible stem.
Do you know if the rubber tape is really required? and what yellow tape width is recommended for a 23mm rim, 21 or 25?
I will be using it with schwalbe one's pro tubeless.

Updating this just in case someone else comes looking for the same info:

I "sucessfully" converted my HED Belgiums C2 (not +) to tubeless today, this is what I used:

1 Roll of 21mm Stan's Yellow tape.
4oz of Stan's sealant
2 Stan's 40mm presta valve
A presta to schrader adapter ($2.5 at REI)
Pair of tubeless tires, I used Schwalbe one tubeless.

Procedure:
* Removed old rim tape.
* cleaned the rim with a cloth and alcohol
* Wrapped the rim with the new rim tap, two laps starting from the opposite side from the valve hole.
* make a puncture on the tape where the valve hole is and put the stan's valve, make sure you use the washer to keep some pressure on it.
* hand mounted the tubeless tires on (before you finish mounting, put 2oz of sealant)

Now for the life of me I couldn't get my floor pump to get the tire to seat, not even using the soapy water trick, so I went to REI bought the presta to schrader adapter and stopped at the gas station to use an air compressor, it worked flawlessly.
Finished pumping with the floor pump and seems good to go, only rode around the block to see if the tire wouldn't come off

Sometimes CO2 will provide the quick blast of gas needed to seat the tire beads and get the inflation started.

What I found is after you use it for while tire won't seat if you ever fully deflate well... that's when you end up using gaffer trick which works beautifully... found out I had to do that when I patched 1/4 cut that I wasn't comfortable riding around (it was plugged up but looked a little bulging until I patched up from inside).

yep. IF the tire is properly prepped. (shape, lubed bead, etc)

I've had tires that I couldn't inflate with a compressor until I removed the valve core. Once inflated it'll keep its shape enough to remove the air chuck and replace the valve core.

Worst case has been a strap wrapped around the circumference of the tire, pulled tight so it causes the sidewalls to push out towards the rim.

But problems of getting a tire to seat on a wide rim are so much easier to deal with than trying to get a tubeless tire onto a narrow old school rim without a center channel. I spent an entire day trying to get a Hutchinson tire onto a DT465 rim a couple years ago, and then close to that getting the second on.

I considered that, but don't you have to let all CO2 go out later anyway? or just keeping pumping it up everyday until it is gone?

Most of the air is lost in trying to seat the bead. Once it's on it holds about 20 psi of pressure. Pump the rest with floor pump. Mines held like a champ a week later
