I am considering to swap a smaller roof box for a wide 900 mm wide roofbox. This would be mounted on existing Thule aero bars with the Thule 755 foot pack.

My roof bars have a clearance of roughly 90 to 94 cm and the footpack "swings" in a little as well. Would the roofbox clamp width fit with the Thule 755s?

 

Does anyone have any experience with a 900 wide roofbox?

Not especially helpful I'm afraid but I have a Thule Atlantis 900 which is 820mm wide.

 

It fits easily on my MkII Octavia on the Thule aero bars.

 

I haven't fitted it on the Superb but when on the Octavia there is loads of room on the rails either side of the box...

 

 

O.K. so it should fit onto a Superb.
