I have a brand new, unused Potenza chainset - it’s black, mid compact (52/36) but chainrings can be switched - same BCD as the 50/34, and 175mm. Powertorque+ which is not quite the same as ultratorque, but actually easier to install and does have a self extracting bolt which is an improvement on the original powertorque. You would need to buy BB bearing cups separately, these are about £20.
Obviously not exactly what you’re looking for, but I wonder if it’s any good to you?
