I just got all the components in the mail today. First order of business is to ream out the inside of the fork (The adapter fits, but stops halfway down). I'm a bit excited
To get us back on track with geometry... I rode a friend's Trek 3 series Madone yesterday on a group ride. It's a 52cm and somehow it felt really small to me. He had it set up with the stem as low as it'd go (with the high-stack headset cap), 80mm stem, and seatpost relatively low I guess. The bike felt pretty nice in a straight line, even though the drops were about where I'm used to having my hoods. However, it cornered like a veritable boat. (I'm not familiar with the geo specs of that particular frame).
One thing I did notice was how light the bike was. It's nothing special, really... standard bontrager components and Shimano 105 with Forte brakes... but it just felt like a feather compared to the other bikes I've ridden.
