EC70 ZERO
FULLY OPTIMIZED
The EC70 Zero utilizes the same overall monocoque carbon construction as the EC90, but with an aluminum upper clamp. This low-profile, micro-adjusting clamp allows easy adjustment and optimal saddle clearance. By incorporating RAD™ Relief-Area Design and TaperWall™ technology, the EC70 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.
