This is off my sons GT Agresser comp with 29” WTB SX19 wheels, disc brakes and a 7 speed Sunrace 17-34 cassete. There are no markings that I can find anywhere on the hub. The removal was different than most I’ve seen. Instead of an Allen key it took a park tools FR-1.3 to unbolt it.
He broke the derailleur. I’m trying to see if there is an option to replace the free hub and go to a new drivetrain with higher gear count.

I should mention it’s a 2021 model year bike in case that helps.
that is a “7-speed freewheel” not a cassette.
