The best pedal for the money,
in my opinion - this illustration
really does a good job of intro-
ducing the concept of the cam
as being the governing factor
in the action of the pedal.
They actually added a Purple
and Yellow cam. I use the
Purple one, btw. It falls in be-
tween the Red and Blue, on
the diagram.
Focus on the shape of the cam,
the rounder, the smoother (as
in the White and Black) and
the more squared, the more
reflex or snap-back (as in the
Red and Blue).
