I have just purchased a 2012 CX9 with roof rails and will soon add the Mazda cross bars. I am looking for a Thule Cargo carrier (or other make) that will fit directly to the Mazda cross bars. The Thule web site does not specify a model that will do this but I have heard this might be incorrect. Any help would be highly appreciated.

 

I just bought a 2010 cx9 & i am getting the Atlantis 1800 with the Thule aero cross bars. This box will fit on the factory rails as well, but those rails are only rated to carry 100 lbs & the box itself weighs 47 lbs . So you can carry a lot more with the Thule rails, however they do cost a lot more. The aero rails are supposed to save you 3 mpg , which is important in our gas hungry cars. The Thule sight says the Atlantis 2100 fits their bars also , but after measuring ,the nose of the box would extend over the windshield by a considerable amount. Fortunately,I work part time at a bike shop so I get wholesale pricing. The 1800 sells for $670 and the rails and attachments cost around $340. So you are looking at a grand for the package.
