This component is a longer version of the standard component found on BMX bicycles. It serves as the interface between the bicycle frame and the saddle, enabling riders to adjust the height of the seating arrangement. For example, riders needing a higher saddle position for comfort or specific riding styles may opt for this modified part.
The advantages of using this longer adaptation include improved comfort for taller riders and the potential for enhanced pedaling efficiency. Historically, BMX bikes favored lower saddle positions for maneuverability during tricks. However, with the evolution of BMX disciplines and a wider range of rider physiques, the need for adjustability and comfort has become increasingly significant, leading to the increased availability and adoption of longer posts.
