With the Guardian rack, it's easy to take a friend and up to 2 bikes anywhere thanks to a narrow arm design engineered to carry most bikes, including juvenile and BMX models. This awesome bumper-mount rack features Saris' pivoting anti-sway bars with rubber hold-downs to keep your bikes in place and prevent them from banging into each other. Plus, foam pads protect your vehicle from scratches. The Guardian comes completely assembled. Just strap it on and go!
