Confersely, if you install a J.I.S. crank on an ISO spindle, it will wind up about 4.5 mm farther in than it would on a J.I.S spindle of the same length.
Confersely?
Anyhoo - I love this little diddy. After making the mistake a few times over the years I have a bucket of bottom brackets and a few cranks. I don't know if they are JIS, or ISO, or WTF. Plus, it does not matter because some of the cranks are used a bit compressed (the tapers). I just slap stuff together until it works.
I know this does not work with new stuff. And I apologize for that. But when splitting hairs over 2 mm here or there I do not believe that even new matched parts are going to work out perfectly every time. (Notice - I said "every" time.)
All that said, know the information above allows you to mix and match your parts and use that too-long or too-short bottom bracket that you got a great deal on.
