The Strada range will fit all UK tow balls, including bolt-on/flange, swan neck and detachable.
Do also make sure that the noseweight for your tow bar is sufficient to take the weight of the rack and all the bikes you will be carrying
Strada bike carriers come with a 13 pin plug. If you have the option you might want to go for a 13 pin socket so you can get functioning fog and reversing lights on the rack. We do also supply a 7 pin adapter so it's no problem if you are using this rack on a vehicle with a 7 pin socket.
