Default Bottom Bracket Education Please

Folks, I'm pretty good with everything else, but BB's have never been my strength. So, I would like to ask a question on how to measure and size. To start I have a 94-96 yo eddy. I've been looking to tear down my BB and clean it up, and thought I should learn some things about it too. Now I did my search and it seems everyone just asks what size they need, etc. What I would like to know is what should I be measuring and with what? I have calipers to measure diameter, etc, so that's a start. Any training/education/guidance would be greatly appreciated. I also have the tools to take it apart and I'll try to post pictures over the weekend. Thanks!

You should have a threaded BB shell which makes things easier. It should be a 68mm size. Axle size depends on crnakset choice.

Kooka cranks require a 122.5mm spindle. Check out this site:
