His principle was a foul from the get go.
even at cruise speeds the road bike will be faster. I also allowed for the condition that his road bike was a retro-grouch bike. In that case his road bike will be as slow as a gravel bike.
on gravel they may be the same speed for him. Once those bike hit pavement the road bike will cruise at a much faster speed with the same effort given.
