Synchroshift on road bikes will work if you have:
Note that you will also need up to date firmware on Ultegra 6870 and that full synchro on the 6870 series is not as great as it could be. The front derailleur somehow limits your switch-from-big-to-small-ring shift point to either of the largest two cogs:
Still, I have been pretty happy with it
- Ultegra 6870
- Ultegra R8050
- Dura-Ace 9070
- Dura-Ace r9150
- GRX
- Current internal battery BT-DN110
- BM-DN100 external battery mount
