Such type of storage won't work for full fender bikes though.
They have racks specifically for fendered bikes....and I have 3 of those racks as they are a little more narrow and they fit the road bike wheel better. You can see it on my domane...it has a lower dip in the rack that the main type. They just slide under the fender. These racks are simple to use and the main reason I went with them is if my wife wants to ride her bike, she can easily remove and put it back by just lifting the front wheel and rolling the bike into the rack. She does not have to lift up to a hook that she could not reach. That was a main complaint I had with the hooks was her being able to get the bike up and down. That is no longer an issue.
Also, they are designed to not have the wheel sit on the floor, I have mine about 1 inch above the floor. There is also a small rear wheel plate for the tire to rest on to keep the tire from marring the wall.
