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.

I did my research on seatposts so you don't have to. This baby is the carbon seatpost you need for your carbon rocketship. It's not only cool to the bones, but it is also functional as all getout. The fore/aft adjustment screws make it so you don't have to swear when you're adjusting that last degree out of your seat. Although when you're done, you will swear anyways because it's so much fun. Dang, just buy this thing now.
Works well. Adjustment is easy. It's light and looks about as good as a seatpost can. My seatpost came with the 7x9 oval rail kit as extra, which the listing explicitly says is not included. So anyone worried about getting that, just know it will likely be included.
Very light and has an innovative and convenient saddle angle adjustment system. Comes with hardware for either round or oval seat rails. I used carbon friction paste and torqued to specifications.
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!
