Hello,
I ran an SRX groupset but I didn't like the massive steps in between gears running 1x, so I bought a empire left hand shifter and a derailleur.
After asking in a group someone told me the RH shifter is the same just with a different name on it.
The rear derailleur a part from the adjustable spring it is a quite longer cage, apparently it can take up to 52t cassette ( i only use with a 46t) and the empire can take up to 34t.
Now with the 2x I use a 36t cassette and it will quite better than with the 46t.
Have a good ride
