Thanks for the reply. I saved all the links. There is a huge amount of information in them. My Passage seems to be stock except the wheels. They are Araya 27" chromed steel with front Shimano and rear Nakno hub. I have not seen at NAKNO hub before. There is no sticker saying built in Japan. It seems heaver than the stated 25 pounds but the wheels may be very heavy and this is a tall bike. I am going to put a good used chain on it and a couple of spokes and ride it for a few weeks and see how I like it. Tires are at the end of there life so it will be for close to home rides unless I keep it and then new tires will go on it.I do have some light weight wheels and tires I can stick on it if the gearing will work. I will try it both ways.
Thanks EddyR
