• I seem to have the same problem. I have the 7600 NJS cranks, and I have been running them with an 110 mm JIS BB, namely Kinex. The chainline is not spot-on, but everything seems to run smooth.
    Until today, I found out that D-A NJS is ISO taper.
    So, definitely I am doing something wrong (or not) since people say stay away from matching ISO and JIS.

    Now, willing to do things by the book, which one is the official BB spindle length and standard (ISO or JIS) for these cranks?
