ABSTRACT:
A two-step and toothless bicycle head shaft bowl set has a two-step locking device making use of two semi-cylindrical members and an upper cover provided with a fastening bolt. The two semi-cylindrical members can be caused to effect the fastening by tightening the fastening bolt of the upper cover. The two-step locking device is capable of effecting an automatic alignment of centers of the component parts of the device in conjunction with arcuate lashing rings. The two-step locking device can also be used to enable the bearings to be positioned at an optimum horizontal angle so as to ensure a smooth rotation of the bearings and to eliminate the gap between two component parts.
