All parts of the rod are traveling at the same speed according to an
observer standing on the accelerating rod.

To an inertial observer, who watches the rod slow down, stop, and
accelerate to the right again, it will always appear that the left end
of the rod is moving slower than the right end, (except for the moment
that the entire rod is stopped.)

To the inertial observer the difference in the speed of the clocks at
the front and back end is accounted for entirely by the difference in
time dilation caused by the difference in velocity between the ends.

If I ever have the time to finish my demo, I'll show that in more
detail.
