A dropper seatpost includes an outer tube, an inner tube disposed movably upward and downward in the outer tube, and a pneumatic and hydraulic cylinder disposed in the outer tube. When the pneumatic and hydraulic cylinder is opened, the inner tube is moved upward and downward relative to the outer tube, and when the pneumatic and hydraulic cylinder is closed, the inner tube is unable to be moved upward and downward relative to the outer tube. A stroke adjustment assembly includes a floating piston and an oil guide pipe disposed in the inner tube and having a bottom end inserted into the pneumatic and hydraulic cylinder. When an oil is output from the oil guide pipe or flows back into the oil guide pipe, the floating piston is moved according to an oil volume, thereby adjusting a maximum upward stroke of the inner tube.
