Abstract
A lightweight, high strength bicycle seat post for securing a bicycle seat to a seat tube of a bicycle frame. It comprises a hollow metal tubular member having a seat tube portion for reception in and securement to the seat tube of a bicycle frame, and an integral head portion comprised of four planar walls diverging in an upward direction to form an open space. A pair of the sidewalls are oriented in a fore and aft direction to the fore and aft direction of the bicycle seat and a pair of end walls which are transverse to the fore and aft direction and connects the fore and aft ends of the pair of sidewalls together defining the open space, which, preferably, is generally rectangular. The upper edges of the sidewalls have arcuate load reacting edges, which define a seat angle adjustment path, and a clamp assembly secures the bicycle seat to the load reacting edges so that the seat loads are transferred directly to the load reacting edges at any seat angle. In a preferred embodiment, the integral head portion is formed by a metal swaging process from an extruded metal tube and the metal tube is selected from steel, aluminum, or titanium alloy. The arcuate load reacting edges of the sidewalls can include a lip which is normal to the load reacting edges, and the clamp parts include washer members which have arcuate grooves for receiving the lip.
