It looks nice but I can't tell what bike it is. Usually, the telling particulars are: weldings, dropouts, seatpost clamp, seatstaus bridge, hadtube, BB. try to put some more pics...
any writing on the dropouts?
any framenumber seen anywhere?
any decals left?
any history on that frame?
any more pics? (looks like it has canti bosses but a good pic would clear this up.)
