Abstract
A vertically adjustable seat post assembly for cycles includes a light-weight vertical seat post formed from a relatively soft high strength-to-weight material, such as a carbon fiber composition, and a relatively hard tubular protective tubular sleeve permanently secured concentrically about the lower end of the seat post. The outer diameter of the sleeve is slightly less than the inner diameter of the seat tube opening of the cycle frame, whereby the carbon fiber seat post is protected by the sleeve when the seat post is vertically adjusted and clamped within the seat tube opening.
