Hey guys, I'm about to purchase myself a shiny new lung-bursting 2-wheeled torture contraption (mountain bike) and, along with that, I need a means of transporting it to and from the gnarly trails. Dudes. I've been looking at a few different racks and roof-mounted cycle carriers, but thought I'd throw it out to you lot to see what you're using. I need one that's capable of carrying two bikes comfortably on the rear or roof of my A4 saloon and isn't going to cost a bomb. Any suggestions/places to purchase, etc?
