New ULTEGRA R8050 Di2 series is “pro-proven” as it is a direct trickle down from DURA-ACE R9150. As a road bike component groupset, stress-free operation is one of the most important features to allow all day riding comfort through our intuitive braking and shifting technologies.
Shimano Di2 is capable to pair with your smart cycle computer (E.g Garmin/Wahoo/Bryton)
NOTE: For pairing your Di2 with smart computer requires updated BT-DN110 internal seatpost battery or BM-DN100 External Battery Mount for proper Bluetooth / Ant+ functionality. Compatible for Dura Ace Di2 9070 or Shimano Ultegra Di2 6870 or and above only.
