Finally going to replace the pedals on my wife's bike. I've had the pedals a year and a half now, but had not put them on.
It's not that I hadn't tried, but I had to get her new crank arms first, since we could not get the pedals off.
She crashed a few years ago, and when she went down, she ground off a large part of one of her crank arms and the pedal spindle. This pedal did not have an 8mm option, just the pedal wrench slot, and that was essentially gone. There was nothing left to grip on the spindle to get the pedal off. So, I just bought her new crank arms so that we could put new pedals on.
