A seat post assembly (100) that is adjustable to an upper, intermediate, and lower seat post position using a locking member (20) and a sleeve member (35) coupled to an actuator (34) for securing and releasing an inner tube (110) with respect to an outer tube (120). The actuator (34) may move the sleeve member (35) to release the locking member (20) from engagement with the outer tube (120) to adjust the inner tube (110) and thus the seat post assembly (100) to the upper, intermediate, or lower seat post positions. The actuator (34) and the sleeve (35) may be biased into an initial position that urges the locking member (20) into engagement with outer tube (120) to lock the inner tube (110) to the outer tube (120). |
