Shimano Ultegra 6870 Di2 Upgrade Kit

This Ultegra 6870 Di2 upgrade is the minumum required to upgrade an 11-speed Shimano road group to 6870 electronic shifting. Shimano has taken all the improvements from their electronic Dura-Ace 9070 group and incorporated them in the affordable Ultegra 6870 group for unbelievable performance at a surprisingly low price.

Upgrade Kit Includes:

  • Shimano Ultegra ST-6870 STI Dual Control Levers with brake cables and housing
  • Shimano Ultegra FD-6870 Front Derailleur
  • Shimano Ultegra RD-6870 Rear Derailleur
  • Shimano Internal Di2 Seat Post Battery and internal battery charger
  • Internal Junction Box
  • 6 E-tube wires and 3-port Cockpit Junction Box

Configure your Ultegra 6870 Di2 Upgrade Kit by selecting the components that have options on the upper right menu, then Add to Cart. Keep in mind, it is helpful to know where the battery is designed to be located on your frame, where you plan to locate the lower junction box (internal or external on the bb cable guide area) and if your frame is factory designed for Di2 internal routing. If possible, also measure from the lower Junction Box to rear derailleur, front derailleur, battery and Cockpit Junction to determine E-tube wire lengths.
