I am old school, or maybe just cheap. I have a Tri double case that I have been using for, oh, maybe since 1998. If you only put one bike in the case, you can get 4 wheels, a pump, tools, gear kit, and maybe a folding chair in the box, all for slightly less than 50 lbs. It's big, and ugly, but I have never had anything be damaged during transit, which includes both across the US and Internationally.
