I found this bike on ebay, the seller doesn't seem to know what the actual model is. He states that it has Columbus tubing, and from the picture it looks like both the rear seatstays and chainstays are chromed. Components look decent although the seller only identified the front and rear deraillers. The fork is appears to be an aftermarket unicrown, but it's Columbus SL so that's pretty good I guess. Anyway, here's the link. Do you guys think it's worth the $600? Thanks in advance!
