ABSTRACT:
A bicycle seat post for supporting a saddle on a bicycle frame. A tube cap is secured to the upper end of a tube and provides a cylindrical-segment upper surface. There is a generally cylindrical concentric inner surface, and an oversize upward passage through both surfaces. A cylindrical swivel pin is in engagement with the inner surface. The saddle has a rigid frame that is to be clamped between upper and lower clamp members. The lower clamp member has an upper clamping surface and a lower cylindrical-segment surface in engagement with the cylindrical upper surface of the tube cap. The upper clamp member has a lower clamping surface and a threaded vertical opening. The assembly is held together by a single bolt, preferably extending up from the bottom of the tube cap, through a diametric opening in the swivel pin, through an opening through the lower clamp member, and into the threaded opening of the upper clamp member, tightening all the members together and to the saddle. Simple rotational adjustment of the saddle is thereby afforded while retaining the saddle in its proper fore-and-aft alignment. Superior strength and ease of adjustment is also obtained.
