Why they thought 116 was a good BCD even though other standards already existed I don't know? The only 116 BCD chainrings are the Victory/Triomphe and some kids one from Miche. If they had done their 135 BCD you could more easily get chainrings and they would probably have saved money not having to make new chainring sizes.
