Bontrager Line Dropper Post 🚵‍♂️ Sick essential upgrade for your mountain bike build. Authentic Bontrager Line internally routed dropper seatpost. Massive 34.9mm diameter with 170mm of travel. Ridden for a couple of seasons but the upper sliding tube is completely clean. Shows normal wear and scratches on the bottom half that hides inside your frame anyway. Perfect for hitting those heavy descents. #mtb #mountainbike #bontrager #cycling #gorpcore
