摘要： A handlebar stem structure includes a tube having two connection members and two extensions are movably connected to the two connection members. Each of the two extensions has two connection ports. An outer layer is coated to the tube and the connection members, wherein the connection ports extend from the outer layer and a first recess is defined in the outer layer. A retaining member is connected to the two connection ports and a second recess is defined in an inside of the retaining member. The first recess and the second recess are matched to form a passage for receiving a handlebar.

摘要： 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.
