I am very new to vintage road bikes. Like I said, this is my first vintage bike. I have done fair amount of reading and hope to learn something from this bike.

I guess the bike had 126 rear spacing originally. I am not sure if it had been stretched to 130, will have to measure it to confirm tonight when I get home. If it is 126 now, I 'd probably prefer to stay with it and build the bike with older parts with 6/7 freewheel.

I noticed the Deore DX hub on the bike now has a few rings (5 or 6, look like spacers?) on the non-drive side of the hub. Is it possible to remove some of them and use the hub with a shorter QR before I find other hub or wheel so I don't keep stretching the bike? Is it okay to leave it like this if it is stretched from 126 to 135? I am looking at a set of vintage Phil Wood hubs to maybe build a set of decent wheels.

According to some older posts here, 1982 (supposed to be 1st year they offered it) has 700c wheels and caliper brakes, but in 1983 and after, they changed to 27" wheels and cantilever brakes. So there are some confusions.
