Hi Fazerider,
I was googling "gearchange selector escapement" (I'm designing a bike and don't want to re-invent the wheel) and came across your harrowing tale. Very impressed at your tenacity in getting to the bottom of the problem. Also very handy for me in understanding the fundamentals of the mechanism. Good job.
But perplexing why that tang was repeatedly bending, given that it was so hard. Just case-hardened I guess, and the core metal a bit too weak for the job. A case of misguided weight saving.....??
