Easton's lightest seatpost yet. The EC90 Zero features a feathery full carbon construction and Easton's exclusive TaperWall technology for extra weight savings and excellent durability.

The two bolt clamp design is easily adjustable and uses carbon upper and lower plates to shave a few more grams without giving up strength. The Relief-Area Design (RADâ„¢) places a flat section corresponding with the clamp zone to prevent crimping.

The EC90 Zero Seatpost features 0mm of setback. Available in 27.2 mm, 30.9 mm and 31.6 mm. 400 mm length. Matte UD Carbon Finish.
