Sorry I have to always seem to disagree but.... There are only two hubs, a 36 hole and a 48 hole pattern ( SJ Heritage Special) H, WM, width, and circumference make little difference. When rims are made the come out of long rolling press and are just cut to size depending on wheel circumference, then bent and welded. I am surprised that they got all rear rims tooled incorrectly as a reg rim has just a 1x1 pattern and the Heritage has a radial lace 2x2 pattern,you would think they would have gotten 1 of them correct. They got all the front rims correct.
