And just for balance, I'll note that I did my "other" kind of commute today -- rear pannier loaded up with a week's worth of clean clothes and a bag of apples to snack on at the office. No idea on the weight, but that particular bike is just under 30 lbs before the pannier, lock, pump, water bottle, and lights when so equipped. It was kind of a slog.

I'll be taking home all the week's dirty clothes when I leave today. Can't wait.
