EC90 OFFSET
PERFECT FORM, FLAWLESS FUNCTION
The EC90 post offers the same groundbreaking weight and performance of Easton’s flagship EC90 Zero. The difference is that this seatpost features 20-millimeters of setback to help riders fine-tune their bike fit. The EC90 utilizes full carbon fiber construction (including the upper and lower clamping plates). And, of course, this thing is plenty strong too. By incorporating RAD™ Relief-Area Design and TaperWall™ technology, the EC90 has been intelligently designed to distribute stress along the length of the post. We also remove material in critical clamp zones to prevent pinching the carbon (which can sacrifice durability).

RELIEF AREA DESIGN (RAD)
RELIEF AREA DESIGN (RAD)
Defined: A flat spot running the length of Easton steer tubes and seat posts, 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.
TAPERWALL™ TECHNOLOGY
TAPERWALL™ TECHNOLOGY
Defined: 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 jeweler-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.
