Holds two bikes by the wheels and frame. Doesn't care what kind of frame you have, it will hold it straight. By holding the wheels, there is zero chance of them rubbing against your car. Some folds so they can be left on the car when not in used. Some also has a lock on that sliding curved bar on top to prevent opportunistic theft.
I had one of those, the problem is that if you have cables routed along the top of the top tube, you have to pad them so the hook doesn't put pressure on the cable and press them into the top tube. Wearing away the paint, and putting a groove in the metal.
