Default TdF and recumbents

And of course, there are the mountain stages, where conventional wisdom
says that recumbents can not climb. The first thing is to throw out all
personal observations here, since they invariably involve recumbents that
are heavier than a state of the art CFRP lowracer and riders considerably
less able than a UCI professional.

Excuses, excuses, excuses!

Ed Dolan demonstrates his ignorance of what is and what is not a
scientifically valid comparison.

The key is to remember that aerodynamic resistance increases with the
square of the rider's airspeed. Therefore, for average club riders, both
upright and recumbent riders will be going slowly enough that rolling
resistance and mechanical losses in the drive train will dominate, which
favors the upright. However, with a professional level rider putting out
400W on a climb, speeds become high enough that aerodynamics does matter,
even on a relatively steep climb, and an upright rider out of the saddle
is not very aerodynamic. Is the aerodynamic advantage of the recumbent at
very high rider output levels enough to compensate for the advantages of
the upright? I do not know, and more importantly, neither does anyone

Aerodynamics is only part of the story. The other part is primate anatomy
and physiology.

Of which Ed Dolan apparently knows little. Has Ed ever read any of the
papers by Danny Too addressing this issue?

Please rush me a telegram if and when a recumbent ever beats an upright in a
professional cycling race in the mountains.

Please rush me a telegram when the UCI allows a recumbent to compete in
such a race.
