Easton EC90 Carbon Inline Seatpost

The EC90 Zero 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. We also remove material in critical clamp zones to prevent pinching the carbon (which can sacrifice durability).


  • EC90 TaperWall Carbon post and EC90 Carbon upper and lower clamping plates
  • Relief Area Design distributes clamping forces across more of the seatpost
  • Compatiable with most 7x9mm carbon railed saddles
  • Two-Bolt Head
