Correct BB Spindle Width for DA crank (circa 1991)?
I have a really old Dura-Ace crankset from 1991, model 7402 I believe. I plan on putting this crankset on a frame that accepts a 68mm English threaded BB. And I would like to know what is the correct spindle width for this crankset. For the 7402 Dura-Ace crank Sheldon lists two possible BB spindle widths (112mm and 113mm) on his BB database page - https://www.sheldonbrown.com/bbsize.html#dura
So, which one is the appropriate spindle size? 112mm or 113mm? I've looked around and can't find a single cartridge BB with a 112mm spindle anywhere! And what does an asymmetrical spindle look like anyway?

Sydney's right on this. Think about it - is 0.5mm (the difference is split over two sides of the spindle) going to make a meaningful difference in your chainline? No.

Thank you Jim (aka Sydney). This is the last correspondence I had with you. I just found about about your death a few minutes ago. Your humor and friendly assistance over years was cheerfully appreciated. I'm still in disbelief. It was only 2 days later since you replied to my thread about my BB that you left this physical world. I had no idea at all, until I read the sad news...

I know that you are up there in the skies somewhere looking down on us. I never thanked you for this bit of advice and for the many helpful responses you have given me. I was wondering why I hadn't seen your name on here in a while. Now, I know. May your spirit live forever. Here's to you and your family.
