In a previous episode, we tore down and cleaned a Fuji-Suntour Vx S mid cage rear derailleur. It has been reassembled, with every threaded and moving surface lubricated. This includes the limit and B adjustment screws, for which someone years from now will be thankful.
Now I really need a front derailleur with "Fuji" emblazoned on the frame clamp. If anyone has one they care to part with, please let me know. A crankset engraved with "Fuji" is also sought.
