New, unused carbon fiber seatpost with 20 mm set back. Somehow I ordered the wrong size so they won't take it back.
Very clean high luster seatpost. It requires a saddle with an opening to adjust the top screw but it will operate fine with a round saddle rails or 10 x 7 oval carbon fiber saddle rails.
I seem to remember that this size fits Cannondale aluminum frames perhaps others that I don't know about.
