crazy when you're wrenching on the bike it seems like changing the cockpit height that much is going to make you sit up like a kite. Then you see yourself on the bike and you think "damn."
Levi Leipheimer used to be the guy to point to when someone confused saddle to pad drop to low.
Well, it all depends on your body type. Levi is a pretty small guy with short upper arms. Anyone with that kind of morphology doesn't need much drop at all to be aero. For a larger person with long upper arms it's going to be pretty hard to get really aero without a decent amount of drop unless you go pretty far in the superman direction.
The point is well taken that low doesn't always mean more aero, and the same pad height can result in very substantial differences in aero depending on your posture. However, most triathletes start out high. And they go wide. And they don't turtle or keep their head down. And they wonder why some other people go faster on fewer watts. Plus, the prevailing wisdom in tri circles until fairly recently was to go with a pretty short reach with upper arms completely vertical. You need to go significantly lower to attain the same shoulder height with short reach than if you extend the reach forward a bit.
The mantra of don't go too low seems to be directed at very aero saavy riders, but there are a lot of barn doors out there that could actually stand to go lower.
