Waterproof cable for Shimano Ultegra Di2 shifting components. It connects the Di2 components with the junction box SM-JC40 or SM-JC41. 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, which are available in different lengths to accommodate most frame dimensions. Connection with PC for diagnosis and changing the shifting order. For questions about the length, contact the Bike24 service team. Fits all Ultegra Di2 components, incl. battery.
Note: For the function of the complete system four cables are imperatively needed to connect the front and rear derrailleur, the battery and the control unit of the STI levers with the junction. A fifth cable is optional for a connection with a PC.
The Ultegra Di2 products are not compatible with Dura Ace Di2.
