Shimano Shimano Di2 Wiring Harness Front/Top Junction SM-EW67-A-E (Ultegra Di2)

Wire kit with control unit for Shimano Ultegra Di2. The control unit offers a battery charge indicator and a rear derailleur adjustment mode. This wire kit is equipped with connectors for the left and right STI. With additional EW-SD50 cables it connects the Di2 STIs with the junction box SM-JC40 or SM-JC41 and thereby with the front and rear derrailleur and the battery. The electric cables include only two core wires (DURA-ACE Di2 has four) and the connectors are smaller too with a diameter of 5.1mm. Easy plug and play system to connect the cables. Connection with PC for diagnosis and changing the shifting order.

Note: The Ultegra Di2 products are not compatible with Dura Ace Di2.
