Question about Thule BackSpace XT Cargobox

Easy access to the boot as the box is attached to the fold-down Thule VeloSpace XT. The Thule BackSpace XT Bike Arm and Thule VeloSpace XT Bike Adapter allow you to transport a bike together with the Thule BackSpace XT Cargo Box (sold separately as an accessory). We have the Thule BackSpace XT 2
When we bought the box we were informed by Thule that this is the only bike carrier that fits this box. We would never want to give this box away again - it is so great! Even just loading it is great and what is important, we have a Volvo Xc40 and if we take another roof box here we can no longer go into the garage! We can only recommend this box, it is worth it! Greetings HB
