|I am still trying to dial in my bike...rode a friend's this nite...felt better than mine, so we started to copy down #'s...I find that on his frame, stem is lower, and my elbow just touches my knee when my hands are on the hoods. I feel comfortable on the seat.
1. On my bike, my elbow is about 2-3" inward of my knee when I am on the hoods...my stem is upright. When I flipped my stem over, and then the height of the bar is similar to his, my elbow overlaps my knee about an inch...
Is there an "elbow/ knee" relationship?
2. Now, fore and aft...on the front of my leg, below my knee is a protruding bone, is this the drop from which I send a plumb to the spindle? I have heard from the knee itself, from some bone on the side of the knee....HELP!...Does a large foot impact on fore/ aft?
3. Where are the seat bones supposed to fall on a seat? on either side of the seat? with the seat up your ass, or do the seat bones sit on the rear of the seat? I find the length of the seat resting on the underneath of my testicles...ouch.

|1 - the general recommendation is that your knees just graze your elbows, but there's so much variation in body position that this is only a general guide. A lot has to do with both personal preference and your flexibility. Your position will change with time as you adapt to the bike and riding style. People generally go "lower and longer" as they gain experience.
2 - you drop the string from the bony protrusion below the knee, but this is only a starting point anyway so again it's not hard and fast. Starting point is also ball of the foot over the pedal axle, so yes, shoe size has an impact. However not much as it isn't going to move your knee much.
3 - sit bones on the "center rear" of the saddle, with the nose of the saddle tilted such that there is not undue pressure on your privates. Very slight changes in saddle tilt have a major impact on comfort.
