Lets try the more polite approach and cut out that one word crap like "wrong" and "fail". I had no intention of confusing the OP with the many ways that might be used to make one brand of shifter workable with another. That's another topic that I too am well versed in. A J-tek shiftmate could also be used to mate one brand of shifter to another brand of RD. J-tek is back in business.

I've figured out a few mismatches that work, myself. My winter bike is setup with Centaur shifters converted to 11 speed with an older Chorus 10 RD, slightly modified.

One potential problem with using the newest ultrashift ergo levers with other brands or models of RD is inadequate return spring pressure. Even owners of Campy Centaur or Veloce drivetrains from '07-'08 have had problems using the 2009 ergo levers. If the RD has one of the weak return springs, the shifts to smaller cogs will always be troublesome. That spring is not sold separately for replacement.

I've not yet read of anyone using the hub-bub cable routing with the new ultrashift ergo levers.

The new ultrashift levers are certainly not crashproof. I broke the ergo body on a nearly new pair of 11 speed levers, last November.
