I'm not buying it. I'd like to see the pics of the drop outs still in the rack, with the bike blown off.
The torsional forces on the drop outs cornering, and braking at 50 mph with a 200lb rider on it have to greatly exceed some wind on the frame.
Also I've driven thousands of miles at 80+ mph with bikes on roof racks without incident, and you routinely see people driving down the interstate with roof racks at high speeds without issue.
