Abstract
A head set assembly for bicycles includes a bearing set with balls received between an upper race and a lower race which is connected to an end of a head tube of a bicycle. The upper race has an annular inclined surface and an annular vertical inside. A pressing ring has an inclined outer surface for being engaged with the annular inclined surface of the upper race, and a flange extending from the inclined outer surface. The flange of the pressing ring is matched with the annular vertical inside of the upper race. The flange is mounted to a steerer tube extending through the head tube. A dust cap is connected onto a top of the pressing ring and a skirt of the dust cap encloses the lower race of the bearing set.
