No. In fact, many amateurs ride on bikes that are lighter than the pros use in the TdF, because the UCI races have a minimum weight limit that does not apply in lower categories of racing. If you want to race a bike with identical specs to that used by Chris Froome, you can buy it.
They are faster because they are more gifted. Tou may as well ask what makes one person cleverer than another.
