I have read/heard this baseless assertion more than once, but I have no
found its source. Probably came from misinterpretation of som
misleading marketing. Fact is, aerodynamics come into play as low as
mph, for any object moving through a fluid such as air. Frontal area, o
area against which fluid is directed, will create drag. Every object ha
an inherent drag coefficient, resulting in a force against the objec
when passing through fluid. That's why planes and cars are streamline
-- allowing them to pass through air with less wind resistance. I don'
need to be an advanced cyclist to recognize that rider position plays
role in wind resistance - i.e. the rider and her bike have a dra
coefficient that varies with position. Generally speaking, reduce
frontal area leads to reduced drag, and reduced frontal area can b
achieved with a lowered rider position
Now, as to the Klein -- I have the Aura X and have about 200 miles o
it. My shop set me up with 3 spacers between the headset and stem
which I assume was to raise me up a bit so I am not falling into i
