I spaced out in my previous post. (Guilty - didn't read most of this thread.) I have one of those steel Nitto posts. Best production post I have ever owned or ridden by a lot. They are gems. Beautifully built, very well thought out and a joy to set up and use. Bought it earlier thi8s spring to have a post I trusted completely on a wild gravel ride that would also mean the clamp would be well away from the seat's ti rail bends. After that ride, I pushed the seat forward an inch to reset the bike to a fix gear. So I have been fooling with that post a lot. And what a joy!
$160 vs $55? If the $55 post works for you, you will probably never regret it. Spend the $160 and you have a post for a lifetime. Worth it? Can't answer that. Now, my Peter Mooney finally has a post as good as the bike.
