There are three major categories of headsets - External, integrated, and semi-integrated, and there are hybrids of upper and lower combinations of the three. External headsets have press fit cups, but the bearings themselves sit external of the frame's headtube. Integrated headsets have the headset cups built into the frame (integrated) and the bearings are held internally. Semi-integrated/Internal headsets use pressfit cups that insert into the frame and hold the bearings inside the frame. The headset for sale is a Semi-Integrated style. The bearings themselves may match that of an integrated headset, but it's wise to make sure the diameters/angles match prior to buying this for integrated use.
