I just purchased a new set of (old stock) Dura Ace 7801 non-carbon wheels. On receiving the wheels found the front wheel hub to show as DA 7801. The back hub however says DA 7800 on the (I believe it is) the left side locknut. Is this normal or is it an early version of the 7801 wheelset? could they be mismatched. I've researched this w/o alot of luck. Can anyone help with this? It would be greatly appreciated as I need to return these if there is a problem w/ the wheelset.
Thanks in advance!
