It is true for all of the cyclists I have observed. Hamstring
length is the main problem, but not the only one. Let's look at
one of Simon Brookes' pictures:

Well, the knee is quite a way from being straight, let alone relaxed,
as it is as you lift it off the ground when walking, but that isn't
the real problem. Look at the other one. It is EXTREMELY bent, and
he needs to put force on it to rotate the pedals. That is NOT good
news for people with many forms of knee problem, and is one of the
most common causes of knee pain when cycling.

Despite the misquoting of the dogmatists, the primary reason for a
traditional riding position is to avoid this, and not to achieve a
low cadence. Assuming that he is the same height as me, my saddle
would be a good 4" higher - to achieve that, I have to ankle, of
course, but it avoids the extreme knee bending.
