For some of their stuff Nitto is very clear about the measurement standard, and for others not. It's an issue for stems, as well.
Holding the seatpost at the 70-ish angle from the vertical, I tend to measure from the centerline of the shaft that goes inside the seat tube, to the center point of the seat rail clamp.
I don't care, really, if my measurement matches Nitto's. I measure so that I can compare a given post with another regardless of manufacturer, to figure out if I should or could substitute one for the other. I don't care about "whether Nitto is wrong."
So where did you get custom seatposts?
