Yeah, I don't think I'd hang a carbon wheeled bike from a utility hook either, but I'm not in that budget range or weight class. I did put some extra rubber tubing over the hooks for the road bikes, because the rims are a little "pointy"

The heaviest bike I usually have up there is my old Bridgestone, at just over 30#; the Cannondales and the Klein are significantly lighter.

I picked a 2x4 with good grain, piloted the holes for the hooks and waxed the threads for good engagement without splitting. It's attached to the wall with a 5/16x3-1/2 lag into each stud. I was more concerned with it pulling out of the wall than the hooks coming out of the 2x4; there's 6 lags supporting the 5 hooks; I'm pretty sure it's secure.
