A top head set securing device includes a C-shaped pressing member connected to a lower end of a ring portion of a handlebar stem which clamps on a steerer tube extending through a head tube. Two lugs extend from two ends of the C-shaped pressing member for a bolt extending through the two lugs to securely clamp on the steerer tube. The pressing member has a tapered inner periphery which is mounted onto a tapered outer periphery of a pressing ring which is mounted to the steerer tube and rests on a top head set on a head tube. The pressing ring exerts a downward force to the head set when tightening the pressing member.
