hey Doug, today when I was standing for a short steep climb on my Tricross, I took a second to look down at where my knees were positioned, and sure enough, they were very much in the space between the drops and the stem. I had never really realized how far forward they are when I stand, especially on a steep hill, but its absolutely not a problem nor do I feel awkward or restricted doing this.
I realize that I can't really take a photo from my eyepoint when standing, but was wondering how it is for you. I did notice that I obviously have to keep the bars relatively straight when I do this, but again, I just do it without thinking or feeling restricted in where my knees are.
It must be very similar with my Troll also.
