I have an old 70's BSA road bike. I want to replace the cottered cranks and chainring with new cotterless ones. I then want to fit a modern sealed BB.
I have counted the teeth on my single chainring and it has 46 teeth.
should this fit :

I'm guessing that all 46 teeth chainrings are the same diameter due to the spacing on the chain?
Also I think its a standard 24tpi BB so how do I know what BB to order that will fit the above chainset.
