Jeff, To add a bit of extra info... There are no Campagnolo spindles that use the JIS taper. All are ISO or old style Campagnolo taper. There are pretty much the same, although (and I base this in my own measurements) one might say that the older Campagnolo spindles are on the "fat" end of the production variation allowed by the ISO. Many old Campagnolo crank arms have had their mounting areas stretched through the years. So, by the time a Campagnolo crank is 40 years old, a JIS spindle is a better fit than an actual Campagnolo spindle. This is one reason that Phil Wood spindles, which "split the difference", seem to work so well with older Campagnolo cranks. By my measurements, TA spindles also split the difference between ISO and JIS, so one of those can also work well with an old Campagnolo crankset whose mounting hole has been stretched. Finally, George mentioned Greg Parker's Web site. It has some truly useful information on this topic. Also, if you do this search, you will find dialogues between Greg, me and others on this subject. You will see where we agree, where we agree to disagree, and where we disagree even while we are in agreement: http://search.bikelist.org/?SearchString=BB%20OR%20bracket&SearchPrefix=@msgsubject&MsgFrom=gpvb1@comcast.net&SortBy=MsgDate%5Bd%5D&Scope=classicrendezvous
