Headrest "101"
People are different.
Peoples' bodies are different.
Your body might be different enough, far enough away from 'normal', to need extra fitting...
to fit your bike to your body.
For example, my little brothers' head is big, angular and square.
All of his hats and helmets have had to be modified to fit his head comfortably.
My head, of course, is normal... not freakish at all.
*ahem*
On the other hand, my brother competes effectively on both of his
beloved diamond-frame road and off-road bikes.
I can't even sit on a diamond-frame bike without pain.
My point is, if your head rest is uncomfortable for you, you may have
to modify it until it is comfortable for you.
-----
I suggest that you relax into your Cruzbike seat, with the bike supported
in a stand, a trainer or something like that.
With your body seated and relaxed, pedal for a few minutes to make certain
that you are fully seated.
Now -easier with a helper- you determine exactly where your headrest should be, for you.
If the stock headrest fits you comfortably, then you're good!
If not, then give this a try:
I did my own headrest fitting, using a foot-long length of solid copper electrical wire.
I molded/bent the wire against the back of my head, along my neck and on to the back end
of the seat... and got my own custom headrest profile.
If you don't have copper wire, well, anything that will bend to shape easily and hold it's new
shape will work.
Thick, heavy wire solder will work well;
soft steel wire will work too.
I used the copper wire because it was lying around, close to hand.
Even cardboard and Gorilla tape will work!
All you need do after finding the profile, the headrest shape that fits you best,
is match it by sculpting your headrest foam to match.
My headrest fits me perfectly.
I hope this gives you some idea of what's possible.
Remember, fit is everything... at least, it sure helps!
