I had a quiet nasty chain snap couple of weeks ago. I was gaping from a bench to a wall and when i got on to my back wheel i knew i had to give it some power to make the gap, so as i putted lots of tention on to my cranks the crappy halvelink chain snaped on me and I have fallen down and kicked the wall accidently, I have dislocated my big toe so i couldn't ride for couple of days.
