Yes, I do believe that - I am sure that we can reach the same speed regardless of the bike.
What I am saying is that if you change wheel size you will have to change something else (power output, gear ratio, cadence...) in order to reach the exact same speed.
If you do not change enything else, only the wheel size - well, the 650 wheel is smaller so in one revolution my guess is that it will cover less distance than the 700.
Maybe I just don't know how it works - as I said I'm not a mechanic - but if I try to just make a few calculations, simple physics says that to reach the same speed with 650's you would have to use the same power output, which on a smaller wheel means higher revolutions or different gear ratio.
Correct?
I am definitely confused
Wisdom from the mechanics/framebuilders/engineers needed please...
