You know you have frame's that you've built different ways. Maybe sometimes even drastically different ways. Post them here and if you wish, some explanation.
I'll go first:
My Miyata 210 came to me like this for something like $35:
I refurbed it so a friend could commute on it:
then I got it back from him and built it like this so I could ride in the winter:
then I needed something for a cross race and the clearance for 700c wide tires was a hit
after that it went to yet another friend in a commuting setup that I don't have a pic of.
And now, it's back to me, hanging as a frame in my garage, waiting for it's next incarnation as a IGH winter commuter. Pics will come of that later.
Next?
