Light, Guaranteed to Perform
The Easton EC90 Zero Bicycle Seatpost is the lightest seatpost in the Easton
line, thanks to its full carbon fiber construction (including the upper and
lower clamping plates). This thing is plenty strong too. By incorporating RAD™
Relief-Area Design and TaperWall™ technology, the EC90 Zero has been
intelligently designed to distribute stress along the length of the post. Easton
also removed material in critical clamp zones to prevent pinching the carbon
(which can sacrifice durability).
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.
Increased durability with no weight penalty.
TaperWall technology infuses Easton tubing with the unique performance
characteristics revered by cycling enthusiasts and world-class athletes alike.
Computer-modulated draw benches allow Easton 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.
Radically enhanced strength and durability and less weight. Lively, responsive
ride quality and improved shock absorption.
