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.
Get up to get down
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.
Need an even shorter drop? Grab a 10 mm or 30 mm travel-reducer spacer.
