According to the Sheldon Brown method of measuring adjacent bolt holes for getting BCD, my Dura Ace track crankset would be the larger Campy BCD and not the standard 144 BCD I was thinking it was. I've seen the plastic template for measuring this at my LBS but I'm sure that someone could tell me without checking. The old fluted Dura Ace track crank was 144 wasn't it? My calipering isn't an exact science but I think the adjacent measurement I got was closer to 88 mm than 84.6. Maybe the info on the Sheldon Brown website was a misprint.
