116bcd, 3 hole steel chainrings
Starting off - newb on this topic and yes, I did a search hereÖ

I have a couple of 116bcd 3 hole cranksets that need chainrings. These will be single speed bikes so Iím thinking ~46 teeth. Are these common or am I looking for unicorns?

Usual thanks and hoping that sharing your knowledge will reward you in the afterlife.

Ones like this Nervar ring on eBay are pretty common, though 46t might be hard to find:

Those 3-arm steel cottered cranksets from Stronglight and Nervar were standard on early 70s Raleigh SuperCourse bikes.

The 3-arm, 116mm BCD pattern was adopted by many manufacturers BITD.

Thanks JohnDThompson. That chart is exactly what I was looking for.

Be aware that there's a couple of different chainring bolt diameters.

There may be unicorns roaming between 49T and 42T, but its not like baiting bears with stale donuts...

You might find a half step chainset, but make sure the chainrings are individual, and not bolted together.
