Seatpost length is measured in millimeters. It is typically measured from the bottom of the post to the center of the rail mount.
Offset is often referred to as setback. This is the distance in mm that the clamp is offset from the center of the seatpost.
Seatpost Material
On a dropper post, this is the distance that the post will drop.
Rigid seatposts are the most common type of seatpost with no suspension or dropping capability.
