Hi everyone, my stock wheelset died on me, so I need to buy a new pair. Two options I'm looking at are anything from lightbicycle or a pair of Hunt Gravel Race wheels

The issue is that finding a wheelset on lightbicycle that has a compatible freehub for a 9spd bike is near impossible.

I'm wondering if anyone has ever used their wheelsets before on a Topstone? Otherwise, I'll go with the alloy gravel race Hunt wheels. This is specifically the wheelset I'd want, but I doubt it'll work. Very new to wheels and stuff so any input would be appreciated.

What confuses me is that they say "Shimano Road 11S works with 11/12-speed cassette directly or 8/9/10-speed mountain cassette with a spacer(s)" for the freehub body. Does that mean I'll be fine to rock the wheels on my bike, with a spacer? And if so, where could I buy the right sized spacer?
