Bontrager Line Dropper Seatpost


A cable-actuated dropper post with infinite travel adjust and a simple, reliable design.


It just works

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.
