Thats a nice notion: I wish Surly would make a BF type frame!! I love their normal steel frames but am now a folder junky. Maybe we should strat bombarding Surly with this request!! Are most BF designs patented or...? don't get me wrong, i'd love to support BF, but my budget is really an issue plus i think buyiong a complete bike only to dump all the components is just senseless. Too bad they don't leave you the other option..

Yeah about the 405 vs. 451 wheel thing. I don't really get it, the added efficiency and comfort of 46 added mm's must be really minimal...? Or am i mistaken? Are we talking a few % here or 10% or...? If it is a tiny increment i don't think i'd ever go for 451.. unless there are other benefits i don't know off?
