The narrator simply says, at 13:06, "It's standard cup and cone". The
bearing is standard, but the shell looks a great deal more limber than
a normal slender hub shell.

Experimenting with the adjustment, I stayed with the "finger tight, hold
the cone and set the lock" habit. That preloads the bearing by the axial
clearance of the cone on the threads. The shell has considerably more give
and might warrant more preload than a conventional hub.

There's no cartridge bearing on either side, per the video.

Good video, by the way.
