Maybe I'm the tool...
I got up this morning to give my bike a good cleaning. Disassembled everything but the BB and headset. Oh...did I mention I was barefoot? Everything went back together just like it's supposed to and I was gettin' near the end and down to the messiest parts, including the chain. I said I was barefoot, right?
So...I sprayed Pedros Cleaner on the chain and gave it a first wipe down. Then I used a citrus cleaner as a bath and wiped that off. Warm water for the final rinse and it was time to dry the chain...without shoes.
I started at one of the chain and pulled it through a cloth so that I was pulling it up and over my fingers and back down (so the links would bend and I could get some of the stuff that accumulates "inside" the links. I did this a couple times, back and forth, and then pulled it a little too far. The chain, with me still holding one end, began it's freefall towards the ground and then, literally, whipped right across my big and second toe.
Most people, including myself, don't frequently experience excruciating pain, but this certainly qualified. My leg nearly buckled and I just stood there, trying not to pass out. The force drew a small amount of blood on the second toe but anticipate some bruising on the big toe.
Next time I'll try not to be a tool.
