Eden's post illustrates how different we all are. I'm taller than her but have a shorter inseam 28". I also have short arms, so, in order to get proper reach on my 44cm frame with a straight tt I need 3cm of spacers and stem with a very steep angle.

To get my handlebars high enough I need a frame with a higher head tube but then the standover is to high. So I need a frame with a sloping tt to accomodate the difference. Now all my bikes have spacers, steeper stems, etc.

I know all of this because the fitter at my LBS didn't recognize my fit needs and out of frustration I went to a Serotta fitter. I had my old LBS make the changes and he laughed, he said "I'd sit up so high that I'd be like the "wicked witch of the west"! Well, now I'm in a neutral position and no more achy shoulders and neck. And I can ride with a flat saddle instead of with the nose pointed down. I bend from the hips when riding instead of from the waist.

BTW, my standover height and tt length was right on, so fit is more than tt length and standover height.

I haven't got the spec's on my new frame. It'll be interesting to see the differences between the old and new.
