Also sustained my first cycling-related injury in years.
The bike in question was stationary. And upside down. I was adjusting the front brake.
Kids, never ever attempt to stop a spinning bike wheel by putting your hand on the rotating disk brake.
ok, it was a small cut, but it fairly neatly sliced the tip of my finger open.
Those things are *sharp*.
I pointed this out to Edward Q. Bean, and said it was an Important Lesson, and that it was lucky it happened to me and not him.
He gave me a Look, as only EB can.
"Well, who would be stupid enough to do that?"
Well put, EB.
