Recently I bought a used CLARK KENT Europa road frame. Need help identifying its history. I know that C-K frames were made in Denver in the 1990's, but as this one has been repainted I am not even sure if it is TI or Steel. Photos available. Clues: frame has nice tight welds, non-lugged. Unusual suspension road fork. TIG welder: "Ivo Dinklarck" or similar. Paint by "S. Soderman." All tubing round, can't tell if it is butted. Metal is slightly magnetic or paramagnetic (responds weakly to applied magnet). Would this frame be suspect as to weld quality? Would like to know how hard I can ride it. See photos. Thx for advice.
