Just bought a new xt. Any suggestions as the best kit to securely mount on the cross bar of my 2012 Rallye with adventure screen fitted. Some mounts are available from Italy but delayed or out of stock. Am I correct in thinking that the diameter of the cross bar is different on these earlier adventure screens than the later ones. Don’t need Whizzy wheel compatability just a good strong adjustable mount and don’t want to use handle bar mount supplied with unit. Thanks. Been searching for hours….
