This listing is for a FSA carbon fiber seat post the that was on my 2006 928L Bianchi. 
It was only on it for a month or two before I found a Celeste logo one. 
The last 2 photos show the Bianchi with the replacement Celeste seaport. 
There are about 17cm of clean seatpost all the insertion marks are below that.
I had about 17.5 cm of seatpost showing above the seatpost clamp. 
Please look at all the pictures. 
Thank you for looking.
