The EC90 Seatposts are the lightest posts in the Easton line, thanks to its full carbon fiber construction (including the upper and lower clamping plates). Available in both a 20 mm and 0 mm offset 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).
