Exactly after trying to use the calculator I came to this forum cause wasn't able to find necessary measurements. My biggest questions were about Hub measurements. Actually all of them.
It's stupid from the side of Cube but Cube zx20 has no measurements of ERD anywhere on their website, I tried to google and nothing.
Probably I will go with DT Swiss M 502 - 29 cause this rims have 602mm ERD in specification and it looks similar to mine but need to do full disassembly of the current wheel to measure precisely. Will try asking Cube too maybe they will share the info.

Thanks for the info! It was very helpful. I will update on my findings cause may be helpful for other owners.
