Anquetil never used ankling, in fact he used a fixed ankle position,
the main difference between Anquetil's style and normal pedaling
is, he never used direct downward pedal pressure. Instead of
round pedaling, he used linear pedaling and this is where his
invincible time trialing pedal power came from because not only
could he combine arm and leg power when riding at speed in the
saddle, he also could eliminate the dead spot area, twice as
successfully as the expensive Rotor cranks attempt to do and
which will eventually be regaded as another expensive failure
unless the inventors can duplicate the advantages and give
continuous smooth pedaling, although they will still have the
disadvantage of not being able to make use of the freely
available arm resistance.
