Great upgrade

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!

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!

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