A method of handlebar stem adjustability on a threadless steering tube bicycle steering assembly and a threadless steering tube bicycle steering assembly. A first step involves providing a cylindrical bushing having a first end, a second end, and a longitudinal slit which extends between the first end and the second end. A second step involves positioning the cylindrical bushing overlying a steering tube in close fitting relation and extending for length equal to a length by which the steering tube extends past an upper bearing. A third step involves tightening a top cap onto the steering tube to clamp down upon the cylindrical bushing to produce compression on the upper bearing. A fourth step involves clamping a stem clamp of a handle bar stem onto the cylindrical bushing, thereby causing the cylindrical bushing to frictionally engage the steering tube.
