I've seen several reports over the years of folks grinding the "hooks" off of worn out sprockets. Have you ever seen that in practice?
We wondered about the worn 24T sprockets on the 14-28T Maillard FWs but never gave it much thought. We just replaced the chains and FWs. Most of them had never been lubed after they left the bike shop where they were purchased. Running dry in the desert southwest allowed lots of dust and grit to do it's job.
Thinking back, most of those bikes had Simplex derailleurs and they may have had the travel limit stops mis-adjusted and or a bent claw hanger??? Anyway, we fixed the problems and tried to educate the owners a little on shifting and maintenance.
