chaadster, I was just wondering whether a little more front end wouldn't help with the problem you mention about being out of the saddle. A little more top tube length, maybe one size larger. It looks from your seat post, spacer stack and your personal measurement description that you chose a bike a bit on the small side. No criticism, mind you. Just observing that you may be getting a little too far out in front of the steering for good control when you are standing. I suspect your choice was due to long legs and a short torso/arms. Anyone else want to comment on this? Would a longer top tube, shorter stem be better for out-of-the-saddle control or worse? How about a slacker head tube and resulting shorter top tube, but longer stem? Would either of those adjustments help in this case?
I know you love the bike, and I am not suggesting you make a change. I am only trying to learn a little about competent bike design from your complaint.
