How do I get/check if carbon wheels are tubeless compatible 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?
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.
