One of the most surprising moments for me was during a descent of a mountain pass on my early 70's touring bike. Prior to that ride, I had ridden new, cutting edge racing bikes for many years. During a particularly steep and straight, and hence high speed, section, I took a hand off the bar (can't remember why, whether to drink of simply shake out an arm) and hit an unseen dip in the road. I was amazed on how little this effected me or the bike. On one of my new, racing bikes, I would have had to quickly grab the bar with my free hand to regain control of the bike, but the old, slack angled, long stayed, low bb'd, touring bike was totally unfazed. That made a big impression on me, and now my only "new" bike is a custom, lugged steel frame with very similar geometry to my old touring bike. Anywho, I can definitely relate to the one handed instability issue with current road race geometry. I personally would not be surprised if this instability is due as much to the higher bottom brackets, as to steeper angles.
