Bikes are sized to the individual rider, even at amateur levels. You can't give a bike designed for a 5'4" guy to a 6'4" guy or vice versa, they physically won't be able to use it. Proportions makes this even worse: the cycling equivalent of Michael Phelps won't be able to use a bike designed for a normally-proportioned person.
