Weight

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.

Seatpost Material

Rigid seatposts are the most common type of seatpost with no suspension or dropping capability.
