They have several types of wheels, some of them require their "podium", which is like a base to which you attach any rim you are interested, some of them are integrated wheels. This one seems to be integrated; regarding flexibility, it really depends on what type of games you are playing; if you play F1 and rally games, it usually means you need an F1 and a round wheel, so podium base might work better for you, but if one wheel suits you just fine, integrated is good enough.
This is definitely a quality bundle and the wheel will work on both PS5 and PC, so it is a good choice, if you are ready to get entry-level premium simracing gear.
