I have the same issue. The problem I'm having is i cant drill a hole thru the left over rod. Do you recommend a certain drill bit? my drill bit just spins and barly makes a dent in the rod.
Definitely needs a titanium or some kind of machine bit. Sometimes you can use a punch and tap on a piece of the broken rod. It may back out that way was well.
I had already bent it a couple times and straightened it back out. I think just the motion of the pedals did it over time after that. Never seen it or had it happen so I thought I would fix it and film it.
