Q. Which is better: car roof racks or crossbars?

Answer

Roof bars, also known as crossbars, are a pair of horizontal bars that are mounted on the roof of a vehicle. Typically, there are two roof bars. A roof rack, on the other hand, will typically consist of over two crossbars and will have a design that is modular. On occasion, the racks will have a predetermined structure, consisting of a predetermined number of crossbars.
