Ah yes you are correct on the seat stays. A bit confusing when the handle bar, stem, derailleurs and brakes matched PRO 10.
That's one shiny PX10 you posted! I'm jealous as mine has a serious case of rusting on the chromed parts. The front forks ain't that bad managed to rub the rust off with kitchen foil but the one in the picture is bad the rust flaked off the chrome from the metal.
