The seat post includes an upper sealhead, a lower sealhead, a shaft coupled to the lower tube and extending through the lower sealhead and into the upper tube, and a piston in the upper tube and coupled to the shaft. The piston divides the upper tube into a first chamber between the piston and the upper sealhead and a second chamber between the piston and the lower sealhead. The seat post also includes a spacer in the second chamber between the piston and the lower sealhead to reduce a length of the height adjustable seat post in at least one of the first and second positions.
