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.
