10 speed - 11 speed mixing

[Njbb1995]

Hey there,
I was just wondering it would be possible to mix, say a Shimano Dura Ace 9000 shifting kit with a 10 speed Dura Ace crank? Could it be possible?
Cheers

Well, the front shifter/der interface for shimano 11s is pretty sensitive to chainring spacing so when in small ring, biggest cog or big ring and smallest cog(highest gear), you may get some chain rub on FD if using a 10s crank/chainrings. Unfortunatley, the new 9000 chainrings are not useable on any other crank, with the 4 arm design. You could also use a Campagnolo 11s crank, same CR spacing.
