I bought a used 44-tooth crankset from my local bike collective. It has a single 44-tooth chainring and I intend to use it for a single speed conversion with a new cog and chain, but I need to figure out what dimensions of those latter components to buy.

Most advice I see online says that single speed and internal gear hubs use 1/8" chain, while derailleur bikes use 3/32" chain. Great! Doesn't help me here: I don't know what kind of bike this crankset came from. It's only got one chainring, but that doesn't mean it couldn't have come from a bike with a rear derailleur and 6 speeds (or what have you).

So, I resort to measuring. Is it as simple as "if'if the width appears to be 3/32", that's what I need"need'? Or are there subtleties in the dimensions of the chain and the chainring that I need to look out for?

How do I tell what width chain my used chainring needs?
