not exactly. The biggest chainring and sprocket *and* the deraillers. And deraillers on triples have more capacity (called long-cage or something). I guess the derailler cage may make a bit of difference here.
And out of curiousity - I searched some more and found what looks like the answer. That post said:
The CN-7900 and CN-6700 will not work on a triple because the chain does not allow enough lateral movement.
This makes sense, as Shimano has been trying to improve their chains recently. They also enhanced it with asymmetric form this time.
So I assume the 5700 series chain will follow the above and also have a supposedly restricted lateral movement.
