What are the common Bolt/base circle diameters for chain wheels?
I'm interested in all of them; MTB, Road, some old ones if they changed standards, 5bolt, 4bolt, other bolt, triples, and doubles too, nothing proprietory or one off though.
Mostly just curious how many chainwheel bolt patterns there are and what they are.
