A bicycle seat height adjusting assembly comprises of a seat post that axially slides into an insert sleeve that fits into a bicycle frame in the place of a conventional seat post. The front of the seat post has a plurality of evenly spaced holes sized to receive a locking pin. The locking pin with supplemental spring is positioned within a generally cylindrical protrusion that extends out from the top section of the insert sleeve. A main air spring is positioned within the seat post to keep the main air spring free from dirt interference, allow the post to fully rise and lower, and enable the use of a maximum height pre-adjustment system. The locking pin connects to a cable that extends out to an actuation lever that is positioned on the handlebars. The opening between the main air springs two chambers is sized to damped the airflow and keep the seat post from rising up too fast. The counter rotational system for the seat post is formed mainly in the insert sleeve to maintain a strong and conventional looking seat post.
