A streamlined design with fewer moving parts and better seals makes for a dropper post that performs consistently and requires less maintenance. The updated Bontrager Line Dropper Post is easy to set up and now even easier to service. The cable-actuated hydraulic locking design provides proven functionality for bikes with internal routing.
