Complete hogwash. In fact, if you see a "bike fitter" come towards you with a level or plumb-bob, run away.

What does gravity have to do with proper bike position (whether it be gravity measured with a plumb-bob or the perpendicular of gravity as measured with a level)?

For example, you could have a perfect bike fit with the optimal position for maximal power output for your body that just happened to include a saddle position that was perfectly level. Then you decide to use a larger wheel on the rear (a change in frame geometry would be another example). Now, you would have the exact same optimal body position on the bike but the saddle would be pointed slightly downward (as to its relation to gravity).

Again, if you see a clown coming at you with a plumb-bob or a level, walk out of that store. The guy doesn't know what he is doing.
