Easton EC90SL seatpost, 20mm setback, 27.2mm

The newly redesigned EC90 SL ISA Seatpost takes our superlight unidirectional carbon and applies our 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.

Easton is also happy to introduce our 27.2 Di2 Battery Insert for use with all ISA 27.2 seatposts. Read less
