Campagnolo Ekar GT best cassette is SRAM 13S?

[VonPG]

Since Campagnolo New Groupset EKAR GT rear derailleur max cog is up to 48T(Old is 44T or less). Is it compatible with SRAM RED XPLR 13-Speed Cassette?(Maybe you should use axs chain and other axs pully wheel)
In this way you don't need to buy some rear hub or wheelset must contain N3W freehub. Just XDR is fine.

Most wheels have easily changable freehubs - like DT swiss. Very easy to do. Honestly, I would say that for SRAM people not wanting to drop $600 on a cassette - EKAR might be a good choice!
