I hope no one minds me switching gears here, but I was wondering if anyone has any information on the Steel framed Swift? Are there any differences between the aluminum and steel ones, besides the obvious materials? Anything major that should steer me away from trying to pick up the steel one? I don't mind about the weight differences. I like the idea that the aluminum one has mostly "normal" parts that are not proprietary to the bike only, so I was hoping that the steel one is along the same lines. Any information, and pictures (if available) would be awesome.
