Open the box, follow the instructions, attach to your trunk, and fasten your bikes and go. It's just that simple with the Guardian 3-bike trunk rack from Saris. The bumper-mount design makes it easy too, so getting it on and off won't be like thumb wrestling a praying mantis. The pivoting anti-sways and hold-downs adjust to almost any bike size, and the rubber-coated hooks and spring loaded metal buckles integrated with the six ratcheting tie downs securely attach the rack to your trunk, accommodating up to three bikes. The standalone arms and legs can be folded out of the way when not in use.
