You would be able to go 22mph or faster on your "road" bike if you adjusted it's riding position, or if it were properly sized to allow you to get into a good position. 1973 Huffy Scout ten-speed:
And that’s why the professional riders all ride their road bikes in a time trial, right?
Oh wait….they all ride TT bikes because of the better aerodynamics.
I can easily go 22 and have sprinted to 33 on my road bike (flat road, no tailwind) but it’s a lot -easier- for me to go 22-33+ on my TT bike, same roads, same rider.
