I don't know if any of these reasons are right. Does
anyone know the definitive answer.
Quoted message said:I seem to remember seeing a table figures for the
differences in aerodynamic drag from different things, leg
shaving, tight vs flappy jersey, hat / bald head vs hair,
beard vs clean shaven. All these things do make a slight
difference. Not that I'd shave my legs, and if I ever had
to, I'd write "shaven under duress" all over my legs in
marker pen...
I'd like to see how they got the figures. My guess it would
be by making "simplifying assumptions". The problem is that
aerodynamic drag is largely due to vortice formation, and
the right amount of hair in the right places can actually
reduce that, i.e., reduce aerodynamic drag. There's about as
much scientific basis to shaving for speed as there is for
helmets saving cyclist's lives.
Don't forget the reason we had to invent science: sometimes
common sense doesn't work.
