According to the product specialist
Pros
| This rear derailleur shifts quickly and smoothly even under load. |
| Switching speed and precision has been further optimised. |
| Shadow technology making it better aligned and protected under the cassette from damage. |
| Shifting speed has increased by 58% compared to the Shimano Ultegra R8050 Di2 rear derailleur. |
| Shifting performance is incredibly good, even under load from a climb or sprint. |
| The only difference between Ultegra and Dura-Ace derailleurs is their construction and use of materials. |
| Accurate shifting performance and high shifting speed even when you're pressing down hard on the pedals. |
| In a semi-wireless system, the only cable connection is between the battery and the front and rear derailleurs. |
| The derailleur needs only be adjusted once and that's it for the rest of your road bike's life. |
-
Cons
| The weight of this mechanical rear derailleur sits slightly higher than previous Ultegra or Dura Ace level models. |
| Can only be used with Shimano Ultegra and Dura-Ace Di2 12-speed groupsets. |
| This rear derailleur is a bit vulnerable due to the long cage. |
