PARKTOOLS;The integrated system uses cartridge bearings that are supported by machining in a specially shaped head tube. The frame may also use pressed rings or retainers inside the headtube. A cartridge bearing slips into these "cups" or supports, and is simply lifted out for replacement. There is no contact with the headtube face. The bearing sits inside the headtube, and references the angular contact. There are different standards within this integrated-angular contact family, and these are not interchangeable
