Careful with your cap!
I really liked this rack, and was impressed with the design. Super easy to install. Sturdy yet lightweight and compact for storage. Worked great with our mountain bikes and my wife's road bike. However, when I finally needed to use the rack with my road bike, I realized that I could not close the door of my cap due to interference with my brake hoods and levers. I would recommend this for use in an open truck bed, or on a limited basis in conjunction with a cap.
