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. |
| 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. |
