The 11's were more designed for hybrids and mtb's with 46 big and 36 middle rings.
700X38 Hybrid 53X12= ~121 gear inches 46 X 11 = ~115 gear inches
Without derailing this into a 'gear inch' thread there are other reasons as to way 11's are really bad cogs.
But, as stated, 7400 series DA hubs are only designed to go down to 12t cogs.
