Chainring compatibility

I think most 110mm rings are compatible. I have put rotor rings on an FSA crank and also on a Shimano crank albeit 130mm but if they fit both I would think that the Shimano would fit FSA.

    Hi,
    I have a FSA Energy compact crankset 110mm on my Focus Izalco 2.0 2013 with Shimano Ultegra di2 groupset, only the crankset is form FSA. I want to change the chainrings with Shimano Dura Ace / Ultegra, are they compatible with this crank and the shifting will be good?
    Thanks

    I don't think they're compatible as Shimano use their own design of 4 arm spider and the rings are shaped to match the spider - look at some pics of DA and Ultegra.

    Be careful - there are often subtle differences that mean mix n match just won't fit - even among Shimano's own stuff they don't necessarily cross match.

    I assume you are referring to the previous 6750/7950 5 arm rings? Even though they have the same BCD as you FSA crank, and they may physically fit, the sculptured design of the Shimano rings would look odd and may stand proud of the spider arms. The FSA rings look more like the FC-R565 10sp and FC-RS500 11sp Shimano equivalent rings to me.
