The Bontrager Line 34.9 dropper seatpost offers reliable and infinite adjustability within multiple dropping ranges to suit riders of all types. A 3-keyed chassis design provides additional lateral rigidity and minimizes play while a 2-bolt rocker head is perfect for fine-tuning saddle tilt. Line 34.9 is also designed with a shorter overall length, which allows more adjustability and frame compatibility.

Need an even shorter drop? Grab a 10mm or 30mm travel reducer spacer.
