Don't forget to put those plastic strips into the channels of the OEM Mont Blanc crossbars!! That is the key to them being silent. Without them my bars were crazy loud!
the suby cross bars are made by Mont Blanc. They have been making racks a long time. Mine is uber quiet and all my Thule attatchments fit! I now have my old school summit box on it--- no redrill of box and I can still open the rear hatch enough to get a 70lb Lab out!!
