man, was beyond me and wonder if it still is but this is how i see that square taper ISO/JIS thing,
u can run that sugino on the square taper (ISO recommnded) but can't then run it on a JIS or visa versa.
if you start running ya cranks on one or the other u got to leave em on there.... there is a thread somewhere on this in mechanics, will look for it in a bit
