For sale is a Shimano Dura Ace Aero seatpost in the popular 27.2mm diameter and205mm length. This is one of the most elegant and beautiful seatposts to ever come out, in my opinion. They are getting harder and harder to fine with this aero configuration.
This seatpost in good shape. There are ample zig-zag marks, mostly below the minimum insertion line as well as a few dings here had there. But it looks good installed.
