This bike, looks like another rattle can paint job, but if it really has a few coats of Polly, then that's a plus. My guess on the component mix is that that Cranks, brakes, and wheel are new and everything else is original. Still, I would say this bike should be priced at $400.
There are a few detractors on this Raleigh, besides the color, as well as some misleading components. The Brooks Saddle is really their racer saddle and not like the hard leather saddles everyone knows and loves. You can remove the outer chain ring on those old Raleighs so that it looks cleaner. On the plus side, nice rear wheel, but a down side at least for me is no brake. Given the mix of pluses and minuses, $300 is probably the right price.
This Shogun looks fantastic and I think you could get more for it, especially if the owner threw on some bullhorns and TT levers.
Good component mix on this bike and with the exception of the lousy pictures, seems rightly priced.
Of course, the true measure of the Fixie-dex is what the bikes actually sell for and in order to get that I would need to do a empirical analysis on the actual sales prices. Using my own score card based on my past bike sales my Fixie-dex comes in at $260. Thus, my Back to School Special is a bit overpriced and that can also be seen by the lack of responses.
