I'm basing my opinion on my Urbanite hybrid frame. It is a functional, tough frame, but it had some pretty poorly placed braze ons-a bottle boss under the FD band clamp, and cable stops that make it impractical to run cantilever brakes-amature design work IMO. The fork that came with it looked cool, but had no clearance for brake pads next to all but the narrowest of rims-silly. It also wasn't anywhere near their published spec geometry-I measured mine as having a 70.5 deg head tube angle, instead of the claimed 72. ST angle was about right. Also, the bare frame, no fork, weighed over 7 lb, if you care about that kind of stuff-not sure if their fixies are lighter. Anyway, my frame handles like crap. Never ridden one of thier fixed gear bikes, but many people seem to like them. Ride it and see what you like.
