My knee is definitely not forward of the pedal axle with the zero offset post. According to the fitting, the 110mm stem was OK, as my arm angle checked out as correct with that stem. My sit bones measure 135mm apart, and my current saddle is 160mm, so I think it is wide enough. I am wondering if it is firm enough or flat enough, though.

I'm 6' 1", and the bike is a Giant Defy 1 - size "large" as recommended by Giant, but 6' 1" is the minimum height for that size. I'm messing with the stem for two reasons. First, so that I can sit a bit more upright and relieve a little more pressure on the perineum. The second is that, with the 110mm stem, I feel like I'm reaching for the handlebar, and have to get down pretty low to be able to bend my elbows a little. But maybe that's how it's supposed to be, and I'm just not used to it yet.

Fortunately, I have not experienced a wobble at high speeds. It's just that when I went from the drops to the hoods, the front end "wiggled" a bit from side to side - it just seemed touchier than I expected.

I wish I knew more about this...
