Another quick question to add to this thread, but first a clarification:
79, this frame is steel. I definitely wouldn't try and cold set aluminum, I just slid my 130 hub into my 126 frame by springing it with my thumbs. Worked great
.
After re-setting my frame, I checked it with a string for alignment and it measure totally dead nuts on (which it always has). I got my wheels and put them in the frame and got it centered in the chainstays using my dropout alignment screws and it looks completely straight with my seat tube.
However, if I measure at the seat stays, my drive side stay is about 2mm closer than the non-drive side. Brake lines up fine, and everything looks good except for when I put a ruler to it. Could this be due to how the frame was built? Or could it be from my alignment even though it string-tests fine? The frame is a Tenax Schwinn if that matters.
