I didn't state it well, but is it better to use the stated pressure on both tires, 100 on front, 90 on rear, or bring the front down to 90 PSI.

Also, this is the bike with bad chain wear. And possibly, skipping even with the old worn chain. (My technique is pretty rough, after not riding a ten speed for a few years. Last year I didn't ride at all, and before that, I was mostly on a three speed.)

Does it sounds like I may be using this bike mostly for garage sales, shopping for her replacement.

In your opinion what vintage bike is going to be easiest/cheapest to find parts for? Or are good parts hard to find?

Of course, I do intend on checking out some brand new bikes, just to see what I am missing. (Until I fall hard for a pretty coat of paint).
