The seatpost offset refers to the distance between the centerline of the seatpost and the centerline of the saddle rail clamp. A zero offset aligns the clamp with the seatpost, while a 15mm offset positions the center of the saddle rail clamp 15mm behind the center of the seatpost. The offset affects the saddle position and influences saddle position and rider comfort on the bike.
