I have some dues cranks that had a middle ring tooth that tore at a shift ramp. Upon disassembly I found a ring bolt missing in line with the broken tooth that probably didn't help. I removed the ring and Machined the tooth with a diegrinder. I left as much as I could, but I wanted to get down to where the tear started. I reassmebled it with loctite on the ringbolts and one new steel bolt for now. My question is has anybody else done this? I'm wondering if it will be fine for years to come or, only a few rides. I've put 50 miles on it and I think it shifts as good as new. Thanks
