Hybrid 7500

I have a Trek 7500 hybrid. It weighs about 30 pounds with tires slightly wider than a road bike and
80 psi, etc, etc. If I average 17 mph on a typical 40 mile rolling hill ride, what will my average
speed increase to if I upgrade to a road bike?

Or put 23c road tires onto the hybrid...

Heisenberg Uncertainly Principle

You have just written the road biking equivalent. Far too many variables and unknowns to arrive at
an answer.

I ride my 28 pound rain bike all winter with 25mm tires. It goes slow.

I ride my 17 pound race bike all summer with 23mm tires. It goes fast.

Take a test ride - you'll notice a substancial difference. With the same effort - I'd guess I get an
extra 3-4 mph out out of the race bike.
