Description

Finish Off Your Dream Build With A Superlight Unidirectional Carbon Seatpost

The newly redesigned EC90 SL ISA Seatpost takes Easton's superlight unidirectional carbon and applies the patent-pending Independent Saddle Adjustment, allowing for perfect fitment with independent seat angle and fore-aft movement.

ISA allows you to refine your positioning without needing to undo your rail clamps for each minute tweak.

Saddle angle is then locked in place so you have the confidence your saddle will stay put after you find your fit.

Available in Zero and 20mm offset, and coming in at 195g, the new EC90 SL ensures a secure fit and a super light upgrade for your dream build.

  • EC90 Carbon mast with full carbon head
  • ISA - Patent pending Independent Saddle Adjustment
  • Taperwall technology
  • Seatpost weight: Zero - 195g, Setback - 200g
  • Finish: Mattle Black UD Carbon
  • Head offset: 0mm, 20mm
  • Length: 350mm with 80mm min insert
  • Quill sizes: 27.2mm
  • Material: EC90 Carbon

Surprisingly good at vibration reduction

I swapped this in for an aluminum post and it was barely any difference on weight but noticeably better for vibration/chatter on my road bike which is running on 28mm tires.

Highly recommended!

This Easton ISA Carbon seatpost is great! Switched from an aluminum post that i was having lower back pain from. This carbon post soaks up alot of road vibrations so much easier on the lower back also much lighter too and easy to adjust . Highly recommend this product!
