i currently ride a giant ocr. i've been having a lot of issues, just generally being uncomfortable on my bike. so i have been doing some reading on bike fitting (compact frames), and one topic i came across was that when your pedals are in the 3 / 9 o'clock positions, your knee on your front leg should be directly over the axel of the pedal.

does anyone have opinions as to the importance of this fitting technique? b/c my knee lines up about 2 inches behind this spot...and i know i'm stretching to reach my handlebars, which is causing arm/shoulder pain. but my saddle is as far forward as it can go, and the bike fits my legs/inseam great (i.e. i'm pretty sure i got the right size). any suggestions on how to move the saddle further up? new seatpost? anything?
