There is a fool born every minute. There will be some posting in this thread:
Giant says that the clean fork crown area, created by placing the disc-brake calipers down at the hub, makes the bike more slippery as the air hitting the new disc-brake caliper – that’s mounted flat against the bike – has already been disrupted by the leading edge of the tire/wheel.
Unlike the new design, the location of traditional calipers (either in front or behind the fork crown/legs) creates “dirty” turbulent air that slows a bike down.

Interestingly, Giant also says that during aerodynamic testing its disc-brake integration produced less drag than traditional caliper brakes.
