Shimano Ultegra Di2 RD-R8050 11sp Short Cage Rear Derailleur

The New Ultegra R8000 group series is "pro-proven" as it is a direct trickle down from Dura Ace. As a road bike component groupset, stress-free operation is one of the most important features to allow all day riding comfort through Shimano's intuitive braking and shifting technologies.

This Shimano Shadow low profile design increases shift stability and minimizes the vulnerability of the derailleur to damage in crashes, and as a bonus it looks super sleek and integrated. It features Shimano Synchro Shift compatibility.
