Very wee; 20 km. Enough to be reasonably sure I haven't utterly flubbed the handlebar re-alignment and to make Aoife look concerned when I get home.
Oh, and cyclists who ignore red lights, stops signs, due caution at crosswalks, and the concept of directional stability, too; I would not want anyone to think I'm prone to excepting other cyclists from the outbreaks of grouchiness.
It was really a lovely spring day, though, and the grouchiness failed to last.
Aside from the handlebar alignment, I found out that the finger-loops on my water bottles (which rotate freely on the neck of the bottle) can rattle like a fender about to disintegrate by knocking on the seat tube. Someone, somewhere, must make really good stainless steel bike bottles, but I haven't found them yet. (The Filzer bottles I have aren't actively bad, but could be improved.)
