Can the RoofBag cartop carrier ride over the cross bars of a roof rack?
Yes, the RoofBag cartop carrier can ride over the cross bars. It is best to first separate the cross bars as much as possible. The installation is most stable when the front of the RoofBag carrier is right behind the front cross bar. The rear cross bar can be under the carrier. See installation diagrams on the Installation page: Cross Bars. If both cross bars are under the RoofBag carrier, the bag may flap and create noise during travel. If the car has both cross bars and side rails, we recommend buying an extra set of Straps for Rack, and using one pair left-to-right on the siderails, and the second pair front-to-back on the cross bars.
