Another Rob Horn shot

I thought this pic, while not showing much of the bike, clearly demonstrates the principal advantage of a race FF. Tiny frontal area. The principal determinant of drag at these speeds, probably worth 20bhp at 100mph.

This is why motorised racebikes are obsolete.

The great thing about science (aerodynamics is a science) – It doesn't matter whether you believe it or not!

Needs a shot with some

Needs a shot with some obsolete motorised bicycle nearby to really put that in perspective. :-)
