I'm in the process of purchasing a vasa trainer sight unseen. I have a truck I can use to move it, but I'd really rather drive my Prius with a roof rack (picking it up as part of a 300 mile road trip). In pictures, it looks like it can be disassembled to the point of having the one long piece of tubing I can tie down to my roof rack. Any info is appreciated, I long for the day of $1 gallon/gas.
