There's "integrated headsets" and there's "hidden" or "zero stack" headsets. They're not the same thing.

Integrated headsets have an angled stop that's machined into the head tube. The bearing is a drop fit onto the stop and the angled interfaces center and align the bearing as the pre-load is set. That, by the way, is the feature that Chris King objects to.

Hidden headsets have cups that are press fit into the bike's headtube. The "hidden" factor simply means that the cup is contained within an oversized head tube rather than set atop and below the head tube as it was on conventional headsets.

I suspect your bike has the second but I can't tell from the photo.
