The Easton EC90 Carbon Seatpost 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 Easton EC90 Carbon Seatpost 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.
Note: Pre owned. Has defect 3" from the bottom (Can be cut at this point) 100% safe to cut. (View Images)
