Is this a normal experience?

Is this a normal event when one purchases a new bike? Does your body have to get used to a new bike? It just seems odd that my cheap Walmart bike did not cause these problems, but my new bike does.

I found when I changed from riding a hybrid bike to riding a road bike, I was ache-y for quite a while - the different position (and the enjoyment of speed) killed me for the first couple of weeks.

As I've gotten more comfy on the bike and more conditioned to riding in a road position, I've found bike fit to be an ongoing project. After a few months, I decided to lower the seat a little more than I originally set up, and a few months later, I've decided that I need a slightly shorter stem.

I think that maybe by the time I've ridden this bike continuously for a year, I'll have it set up completely how I want.
