Now that I own a tandem (see my thread below regarding my new Cannondale), I want to explore transportation options so that I can do some rides that are not accessible by public transportation. I think that the way to do this is by means of a roof rack. I won't mess up my car (or my bike) with a trunk rack and while I would prefer a hitch rack because they are so much cheaper, I don't think they will work with a tandem.
So, assuming a roof rack (but feel free to pipe in with other options), what parts do I need? The base rack system itself from either Yakima or Thule (about $350) and then some kind of mounting mechanism for a tandem (about $325, e.g. for the Yakima sidewinder mount)? So that is $675 alone and it does not allow me to carry regular (1/2) bikes? Will this rack work on my next car? Will the tandem mount?
Thanks for any help on this. If there are any useful links, that would be helpful as well.
