I understand. To answer:

My "nice white garage doors" are in SERIOUS need of pressure-washing as I've been landscaping closeby and the dust is horrible.

The stem is actually a borrowed 17 deg one, just an experiment to see if my problem lower back likes it better than my 7 degree.

The crosschain situation is not how I rode it last; I put it on a stand and went through the cogs to check the RD adjustment. I just didn't think to run it back the other way before I put it down.

That is a 2005 model mauve wall, thank you. (Actually when we built the house, my wife and I both hated how that color came out, but we decided we'd rather move in now and repaint it later.)

I'm glad I'm learning the picture protocol so we can get that out of the way. I'll be sure and follow procedure next time.
