The KS Cantrell is a parallelogram-suspension seatpost that soaks up trail chatter before it reaches you, with adjustable spring preload so you can tune the feel to your weight and riding style.

Highlights

  • Parallelogram suspension system smooths small bumps and vibration
  • 3D one-piece forged seatpost construction
  • Built-in spring with easily adjustable preload
  • Available in 27.2mm, 30.9mm and 31.6mm diameters
  • 350mm and 400mm lengths

Comfort, not drop

Unlike a dropper post, the Cantrell doesn't change saddle height on the move — it's a fixed-height seatpost that uses its parallelogram linkage to absorb shocks and vibration, bringing some full-suspension-style comfort to hardtails and gravel bikes.

Compatibility & fit

Choose the diameter that matches your frame's seat tube, then pick a length that gives enough insertion for your frame and desired saddle height. Our workshop can check fit and set spring preload for your weight.
