I've got over 10 years as a team mechanic for pro teams here in the states. Hanging bikes by the wheels in a moving vehicle or trailer would be stupid. They'd swing and get damaged. In a team truck or trailer the main constraint is space. The other important fact is that those bikes will have different wheels installed nearly every time they're taken out of the truck. Sometimes training wheels, sometimes climbing wheels, sometimes wheels for flat races. Since they're in a TRUCK, which moves, and they all have carbon wheels, the risk of damage from road bumps is possibly a worry. I will repeat...storing a bike in a room by hanging it from the wheels is not risking damage. Especially if it has aluminum rims like the bike the OP is talking about.
