My pedal (DK Ironcross flats) on my drive side decided to eject my foot on a mad bomb racing cars down a slight downhill street during a lunch hour ride last fall. The chain was an apprenice as it jumped my cog right before foot ejection. Not only did it eject my foot but decided to take a bite out of my lower calf. I now have 4 pin shaped scars in a diamond pattern to remind me of my incident.
