The seatpost diameter must match to the seat tube diamater of your frame. If replacing a seatpost, you can usually find this measurement etched near the bottom of your current post.

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.

Seatpost Clamp Style

Weight

Dropper posts have the ability to change heights. This has become a choice for mountain bike riders that prefer multiple riding positions.

Suspension seatposts are designed with comfort in mind.
