Is 20-21cm too much? This, of course, is for a compact frame.

What's the minimum insertion requirement stated by either the frame or post manufacturer or what is the minimum insertion line on the post? There is no maximum amount of post showing if you meet the minimum insertion requirements. As an example, Giant has a minimum insertion requirement for posts on their NRS mountain bikes. They intentionally use a shim, which acts to strengthen the seat tube, and a smaller diameter post. If you remove the shim and use a larger diameter post they require more insertion to maintain the integrity of the seat tube.

As long as your seatpost is inserted past the seat cluster of the frame (yes, like minimum insertion), it should be good.

Okay, with compact frames, I guess we're seeing some extreme examples of long seatposts, a la the MTB crowd. In fitting your bike, with seatpost height set properly, one should hope that the drop to the bars is not too far. If the drop is too far, get a bigger frame. IF the drop is too little, get a smaller frame. Of course, riser stems and spacers will fine tune your setup, but don't let the stem police catch you ;-)

I just go to the current pictures of the pro bikes in the cycling magazines and copy them. It's fun and a good excuse to tell my wife on why I need to upgrade. Can't wait till next year. LOL

My crotch hurts just from looking at the picture. I can't imagine anyone being trully comfortable on that for any distance
Must be 8 inches difference tween seat and bars. (nm)Spoke Wrench

We abide.

Be the bike.

Old standard used to be one fist, but nobody .....cory

Back when people rode bikes that fit, the standard was to close your fist around the seatpost, and if your hand couldn't cover the exposed portion, the frame was too small. For whatever reason, a lot of people insist on smaller frames now, so that rule's not followed. Rivendell still recommends it, and it works for their frames, at least. I've never been as comfortable on a bike as I am on my Atlantis.
