I very much doubt that an older touring bike with 32mm tyres was faster
than race bike with 23mm tyres, you need to be comparing like with like.

I think many people could use a review about what actually makes a bike faster for road riding. There are always a lot of myths circulating.
One way to think about the question is to first list what are the physics of resistance to forward motion? What actually slows a bike down? Where does the lost energy go?
