Bought the 7x rack. It’s a solid rack. It’s pretty easy to load and unload. The bikes attach securely and I don’t really worry about hauling $25,000 worth of bikes on this thing. I didn’t get the cable lock option because I already own a 15’ cable lock. Using that to lock the bikes to the rack is pretty simple. I like that the only contact point between the bike and the rack is the tires. I don’t worry about frame damage or scratches. The tensioning bolt for the hitch receiver is kind of a pain. I wish they’d use a knob like most other racks I’ve owned. With the bolt I’ve got to bust out the tool box every time and get out the wrench. I don’t have the right size socket, so if I want a socket I’ll need to go buy one. It’s a minor inconvenience on an otherwise stellar rack. I’d still buy it again. If they want to stick with the tensioner bolt, it’d be nice if they threw in a socket to help a brother out. That’s the only downfall I see on an otherwise excellent bike rack.
