According to the product specialist

Pros
The Shimano GRX 11 speed rear derailleur can be combined with Shimano 105, Ultegra and Dura Ace 11 speed groups.
Thanks to the extra tight spring tension on the cage, the derailleur won't rattle on bad or unpaved roads.
Ideal for long rides on cobblestones, when a road bike rear derailleur falls short sometimes.
A long cage (GS) is compatible with these cassette ratios: 11/28, 11/30, 11/32, 11/34.
Easily adjustable with its adjusting screws and cable adjusting screw.
The GRX 12-speed rear derailleur is suitable for cassettes up to 10-51T, when combined with a 40 or 42 tooth front chainring.
This rear derailleur is designed for shifting gears smoothly and quietly, even on dirt roads.
The relatively high spring tension on the derailleur cage prevents the chain from slapping while you're descending.
Thanks to this derailleur you can use a larger cassette and so cycle at a smoother pace.
This derailleur has an industrial look.
This derailleur can only be used with a single front chainring.
Cons
This derailleur isn't compatible with cassettes with a smaller ratio than 11/30.
-
This derailleur can only be used with a single front chainring.
