1x, 2x, 3x chainring - does it matter?
Chainrings designed for multispeed systems have special pins and ramps in them, to assist shifting. Key word being assist. If you have rings for a certain config, it might not have those features in the right spots.
If you don't have them, shifting won't be as good as it would be otherwise. That doesn't necessarily mean it'll be complete garbage either, people happily rode bikes with &quot;plain&quot; chainrings for decades, and continue to do so today. But it won't be as crisp, or you won't shift as well under power, but you'll almost surely shift well enough.
