I thought that may have been the case with the X Frame, but wasn't sure about that either. I hope that is the case. Thanks for your reply!Am I wrong but isn't the x frame symmetrical? So if that's the case I would but the same bag on each side at least in my opinion just as an optical thing. I'm not taking my 600lbs of tenere into places that I'm really worried about width to the point of losing 10L of storage. I have 2 35L on the givi outback racks which is offset and I want the X rack to remedy that.
