Just to be clear John, the AT crankset is totally unrelated to the Maxy. It was Sugino's first generation of what we could consider the modern touring triple crankset. JIS 2 degree taper, 110/74 BCD.
30 years later Sugino is still using that standard. I give them high props for this, unlike Shimano who in my opinion has really f'd things up with all the BCD's they have made, and trying to reinvent the BB every 5 years.
