If a touring and road bike are made of the same material what is the difference?

The reason I raise the question, it appears one could change out rims and tires on a touring bike and have a road bike. I am sure its not so simple but it appears as so. From my humble perspective it seems why get one when you can have the best of both worlds when that option is not such a bad idea. I honestly don't know thanks for your consideration.


Answer
I was hoping someone would actually provide the correct answer instead of just suffering diarrhea of the mouth.

The difference between a DEDICATED touring bike and a race bike are gigantic, and it has almost nothing to do with the materials:

Frame geometry is different (since your question pertains only to the frame/fork). The head tube and seat tube angles are much more slack, the chainstays are longer, the center of gravity is lower to add to stability, and there are bosses added to allow the addition of accessories, and the tubing, regardless of material, tend to be thicker.

There is a "combination" of a touring bike and racing bike. It is called an audax. Still very much a road bike, it pretty much splits the difference between a touring bike and a race bike. It has some of the construction of each bike, for example it may have a variety of bosses such as those that hold racks and it may use lighter tubing have other considerations to make the bike higher performance.

Can you use a touring bike to race? Sure, but you probably won't be competitive. Can you use a race bike to tour? No. They are typically not strong enough to handle the extra weight of various accessories and are not equipped to handle it anyway. Loading up a race bike (if you could) would leave you with a very unstable and hard-to-control bike.
