Shimano DI2 junction box

This new Cockpit Junction 2-port junction box with two cable connections is fitted into the end of a road bike handlebar and serves as a charging socket and Junction Port A. This allows for a visually tidy routing of the Di2 cables. Some manufacturers also offer frames with a mount for this port

The Di2 Cockpit Junction Port A accommodates the supply cables and the cable from a shift lever, and transmits the signals to Junction Port B. The right or left shift lever is connected to this port. In addition, the Di2 Y-cable EW-JC130 is required to connect the second shift lever and route the signals to Junction Box B. Sjhioman recommends the EW-WU111 wireless unit as a connection to the cable leading to Port B. Alternatively, the EWJC200 connector can also be used for this purpose. The gear shifting can also be fine-tuned via the Junction Port. At the same time, the EW-RS910 port serves as a position socket and battery indicator.

A handlebar model with internal cable routing is required, or the handlebar end must be drilled to route the cables externally beneath the handlebar tape.

On frames with a mount for the EW-RS910 junction port, this is then routed behind the EW-RS910 wireless unit or the EWJC200 connector.
