A much better way of wording what i mean't. There will be a reduction for the person in front, but it will be so small, it will be hardly noticeable.

But now you've got me curious why does a drafting cars/bikes/whatever reduce drag on the leader? My guess is that there is a low pressure area behind each rider, but it is greatest on the last in line, where the "envelope" closes. However, the drag is insignificant relative to the frontal resistance (and insignificant, period, at cycling speeds).
