Nice! I have the Thule Force Xt Cargo Box XL (
https://www.thule.com/en-us/cargo-ca...t-xl-_-635801) that I’ve used on my 2014 Countryman and the overhang wasn’t too bad. I suspect it will fit a bit better on the X1, but won’t be able to find out until I get the roof bars. I did have to swap the stubby antenna out for a super stubby, so interested to see how that all fits over the shark fin for that size box.
