Chainring BCD Question
Hey
I've got a quick question
What would be the most likely BCD on a 1979 Sugino (motobecane) Crankset?
Thanks

That's the 1979 motobecane catalog. My bike is a grand sport so it's a sugino 2NJX 2D crankset

The pictured crankset very much appears to be a 110mm bcd Sugino Maxy. See close up showing big drop down from the small ring's teeth to the bolt circle, has to be 110.
