Whatever saddle is installed on a bike, I find it necessary to adjust it repeatedly, in small increments, so that I'm comfortable on it: not constantly sliding forward, not with the nose "impacting" my groin. I find such a place on all types, and it's usually slightly nose-up. Though I try to guesstimate when putting a bike together, that doesn't really matter -- don't think I've ever gotten it "right" straightaway. I pity anyone who doesn't think about this when setting up a bike, or bother to go through the exercise; it makes a great deal of difference, as much as saddle height, in the comfort of riding. And, if I change something like the style of bars on a bike, I need to go through it again, since everything's relative to the other things.

A 2-bolt seatpost makes such fine adjustment much easier than a single-bolt type.
