So, I have cold set my Gazelle frame to 130 mm (from 120). As I was a bit strapped for time the first day i worked on it, I only spread it 5 mm. When I came back the next day it had gone back to 120mm. I was immediately surprised but then the duh moment kicked in and I realized this steel has been at 120mm for 35 years. So, I spread the thing all the way out to 130mm the next day and popped a wheel in to keep it from going back.
The question is, am I not spreading it enough to get past the 'memory' the metal has or is this just the way things are? Do I need to over spread a bit and bring it back?
The way it went back, I'm worried that my alignment won't stay right.
