American Classic seatposts have a 1" setback and infinite adjustment.

I had one of their old-style seatposts on my race bike back in the day, when their machine shop was a 25 mile ride from my house. I really liked it. I guess I could pull it off and put it on the new bike, except it's yellow and it would really clash . Anyway, I don't know anything about the new style beyond what the website says.
