Thule's Archway 2 Bike Rack is designed to remedy all the problems that have plagued trunk racks for years. It won't damage your car's finish, it won't allow the bikes to sway, and by not allowing the bikes to sway, it prevents damage to the bikes (and your car). The Hold Fast cradles accommodate two bikes with relatively straight top tubes, and there's an integrated locking cable to reduce the risk of theft.
