i have a tt bike with all da 7900 and a fsa gossamer pro and i want to change my crankset out to the k force light. i've seen a few places where they say there's a different crankset for the da 7900 as opposed to other 10s groups due to the asymmetrical chain. however i can't find any different part #'s on fsa's site and most retaillers don't show any different cranksets. will i have any issues with this?

In practice, it'll work ok, but if you'd rather have a symmetrical chain, the Ultegra 6600 chain continues to be available since Shimano designates it as the preferred chain for their triple cranksets.
