EC70 OFFSET
IMPRESSIVE STRENGTH, MINIMAL WEIGHT
The EC70 seatpost utilizes a forged aluminum head bonded to a carbon fiber shaft. This combination delivers an impressive strength-to-weight ratio in a more affordable package than the flagship EC90. This seatpost also benefits from Relief-Area Design (RAD™) and Taper-Wall™ technology for pin-point strength, stiffness and durability. The clamping mechanism provides 15-millimeters of offset to help riders fine tune their bike fit.

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.
