Seriously before Phil Liggett's never ending sausage fest over Lance, no-one ever considered cadence to be better low or high. Just whatever worked for you.

Now cause Lance rode at 100RPM give or take, it's like some truth that this must be the perfect pedaling style.

I ride track all summer, and find I start the road season, in the 100-110 range, and by the end of the season am riding around 90-95. I don't perform any better or worse either way.
