Roberto - I've seen the South-o-the-border tags in your pics before, but never caught an explanation.
I've carried bicycles for years. I started out with trunk lid carries and graduates to Yakima roof top carriers which I've had mounted on two different Blazers, a Tahoe, my wife's SRX, and a Honda Civic I owned until recently. On the Traverse, though, I anticipate getting a hitch rack. But, the kind I want is the kind where you have two trays where you mount bikes via their front fork quick releases in the same manner they mount on a roof rack. That seems most secure and will keep them from swinging and possibly bumping against one another. Just my preference.
In case there are any hard core cyclists out there, I have a pair of Colnago brand road bikes - a Dream Plus and a C-40 - that I ride on club rides and centuries. Not to boast, but Colnago is kind of like the Ferrari of bicycles.
