I have fake Zipp 404 and Continental GP4000 SII tubular on it. It is time to change it.
The question is how do I know if this wheels
- a) without removing
- b) with removing
tubeless compatible or not?

1Not a dupe, but here's a question/answer on replacing tubulars. bicycles.stackexchange.com/q/66548/19705 You need tape or glue, and about 3 days total. And ways to remove the old glue from the rim.– Criggie ♦Commented Aug 26, 2020 at 1:53

1@Criggie My friends tell me they exchange spare pre-glued tubulars mid-race faster than they would exchange a tube. I have no personal experience though.– Vladimir F Героям славаCommented Aug 26, 2020 at 6:25

@VladimirF Noone changes tubular tyres in a race. They would absolutely swap a wheel out from the team car or neutral service support though. Using the proper tape is quicker than glue, but it still has to sit under pressure for a while to set up– Criggie ♦Commented Aug 26, 2020 at 11:24

@Criggie There is no such support in those amateur triathlon races. And no teams, the less team cars. They do indeed swap tubulars. Check, for example, forum.slowtwitch.com/forum/Slowtwitch_Forums_C1/…– Vladimir F Героям славаCommented Aug 26, 2020 at 11:35

Tubular rims are never compatible with tubeless tires.
Tubular rims have a slightly concave bed that the tire sits on. Tubeless tires are a variation on clincher tires, and require sidewalls to retain the tire bead.

1Concur - Second way to test is deflate the tube, and gently lever the tyre up. If it is glued or taped to the rim, its a tubular and you can only replace it with another tubular tyre. If the rims are known-fakes then the tyre could be too.– Criggie ♦Commented Aug 26, 2020 at 1:49
