27.0 aero seatpost - 23cm+

[FINNEY1973]

i'm looking for a long 27.0 seatpost of the aero variety - Campagnolo / Shimano or any other that fits the bill.

Needs to be long - 23cm+ - it's going onto a TT frame. Silver in colour, I don't mind if it's a bit tatty as I'm happy to polish it up.

Thanks
