A set of extra long wheel straps that make it possible to transport very big fatbikes. The design is optimised for the best use of space, aerodynamics and vehicle adaptation. Easy to install, thanks to the extra wide preinstalled quick-attachment PowerClick. The integrated torque indicator "clicks" when it has been fitted correctly, making mounting fast and safe. Easy to open and close in all circumstances, thanks to grip-friendly handles and lifting arms as a support. The SlideLock system with separate locking and opening functions. Locks the cover automatically and indicates when the box is properly closed. Full access to the luggage compartment without the roof box being in the way, thanks to its protruding position on the roof.
