I have a new car and the hitch is 2" but my bike rack is 1 1/4" so I needed an adapter and I also wanted one that would give me a little more Free space. from the car, so I went for this style. It definitely does the job. There is a slight rattle, but I'm sure adding an anti-rattle device will solve this problem quite easily. Overall a great product and Curt is a reliable company who also made the tow hitch for my SUV.
