EastonEC90 SL ISA Carbon Seatpost(Return to Product Page)

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!

Super easy to adjust and very light.

Great seatpost does what it suppose to do, saddle is always secure was much needed to help reduce vibration from gravel.

Love this seatpost! Super easy to adjust and love that you can isolate certain changes so you don't totally mess up your specs if you just want to make a small tweak. Worth the investment!
