Being a mechanic takes a sharp eye for details. It’s impressive and appreciated to see those observational powers in others as well.
I recently built up a cyclocross bike for the season and while at the course the other day, I thanked a fellow mechanic for his recommendation of the Paul Chain Keeper. As he was seeing it on my bike, I notice him look at the crankset. I interuppted the question he was started to ask, “Did you…?” as I knew exactly what he was getting at, I replied, “Yes I did.”
See, Aaron from the Mountain Bike Depot obviously recognized the incongruous pairing of my cranks with my chainring. An FSA 110bcd chainring doesn’t fit perfectly on a Campagnolo CT crankarm. Did I file the millimeter or so of material from the FSA ring for it to fit? Yes I did. Both may say 110bcd, but Brand C has to be different don’t they?
Like they told me back in my baseball years: good eye!

it’s not just campy either. i’ve had to file shimano rings to fit sram cranks too. and the other day trying to replace a bent sram inner chainring with a shimano and then an fsa ring i found the gap between outer and inner rings is different w/ each ring. the chain would fall between the rings when i used the shimano and fsa rings. and all our dealers are out of truvativ rings in the size i need.
sheesh.
chain rings appear compatible but really are borderline proprietary.
