As long as the tooth count difference between the big and middle rings is the same 10t as the 9s Ultegra/105 triples or the 8s 105/RX100/RSX triples, the derailer should work well.
Exceptions are "flat-bar" mtb and road derailers or anything made to work with a 52-39-30t crankset, which won't work well if at all.
