Easton Haven Carbon Seatpost

We’d like to think that we’re above boasting, but we’re pretty enthusiastic about the Haven Carbon seatpost.

Developed as part of our new Haven All Mountain group, this new post whispers to the scales at just 240-grams (31.6 diameter x 400mm length), but exceeds the strength of heavier aluminium posts. How so? TaperWall design puts just the right amount of material where it’s needed and RAD (Relief Area Design) helps to ensure that the Haven post can be clamped securely without harming its carbon shaft.

Taperwall Technology: TaperWall technology infuses our tubing with the unique performance characteristics revered by cycling enthusiasts and world-class athletes alike. Our computer-modulated draw benches allow us to create multiple tapers in the same tube, so the tube walls can be reinforced anywhere along their length with incredible precision. The result is jeweller-smooth walls that eliminate the stress points typical of other manufacturer’s tubing. Strength, weight, fatigue life, and responsiveness are all enhanced. Easton also applies TaperWall technology to out carbon components. This enables us to apply more material to wall surfaces where stiffness is paramount and less material to areas requiring more compliance. Advantage: Radically enhanced strength and durability and less weight. Lively, responsive ride quality and improved shock absorption.

Relief Area Design (RAD): Defined: A flat spot running the length of Easton steer tubes and seatposts, corresponding with the clamp zone of stems and seatpost clamps. Removing material in these critical zones prevents clamping forces from pinching and damaging carbon tubing. Advantage: Increased durability with no weight penalty
