I have a 21 inch miyata 610 touring bike. I'm fairly certain it's the 1984 model. I'll try to get some pictures soon.
I'd like a 23 inch touring frame. Let me know what you have.
I have extra parts that I will put on the frame, so I don't need any components, so frame for frame is ideal. But I don't mind trading the parts with the 610 either.
