27.2 Deda Metalstick seatpost. I rode it about 40 miles and bought a shiny silver one instead because I'm vain. It has some small insertion marks. $20 to your door in the USA. See pics.

I also have a well used Tiagra triple (52-42-30) crankset, bb, and front and rear derailleurs. Feel free to make an offer or let me know if you want pics.
