My SanRensho (3Rensho) is cleaning up nicely, after twp days of TLC. I am still waiting on Cyclone or Superbe 172.5 cranks, but I have overhauled the brakes, and cleaned and nail polished the frame, adjusted and lubricated, new hoods, polished the brake levers, new cables, aligned the derailleur hanger etc.. etc.... One rim has been dented and although it is now true, I might need to replace it. The problem is I have never seen one like it. It is a grey anodized 700 c clincher rim that is ultra narrow. It measures only 18mm from outside to outside. It sort of looks like Mavic MA40 but in grey and on a severe calorie restricted diet. There are no identifying stickers, but the clues are that the eyelets are silver but on the inside box section they have oval lips. On the inside is printed #320304S in small black numbers. This is a long shot, but amoung such fellows, even a long shot often enough comes in.

P.S. Thanks to the list member J. Morrison who sold me this lovely 55 cm bike...You might not recognize it now.
