Nitto 65 seatpost. A beautifully-finished single bolt post with serrated interface between the upper and lower cradles. Used to have some issues with the cradles slipping on my Campy SR posts, but not here. Plus, the post is longer (250mm) so should suit a variety of uses - and they can be had for as little as $50 brand new in box.
Set it and forget it - and this recommend is coming from an avowed Campyphile
