A reliable dropper seat post with a 3-key chassis design that minimises shaft play for a post that provides smooth and consistent travel adjustment.
The Bontrager Line 31.6 dropper seat post 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 minimises play while a 2-bolt rocker head is perfect for fine-tuning saddle tilt. Line 31.6 is also designed with a shorter overall length, which allows more adjustability and frame compatibility.
