This last year I saw many West Coast drivetrains. I have done a lot of research since the end of the season, but there is one part of it I can not figure out.

I need help understanding how the drive power from the chain is transferred to the wheels. I have looked at all the individual parts online, but I still do not understand it. Is there a cad file explaining it? Sorry if this is a dumb question.
