Is one taper longer than the other, and if so, which side is DS and which is NDS? I've found conflicting info on this subject.
I was trying to show manufacturing variables, especially between 2 supposedly identical Stronglight spindles.
Up through the late 70s most BB spindles were asymmetrical.The drive side was longer.
One other thing, on used crank arms there is not that much difference between JIS and ISO tapers... Per Sheldon Brown (rip), it fits it works!
I think that I posted some notes with the pictures,
