The Dura-Ace Di2 SM-EW90-A Junction is a vital part of the 9070 Di2 series, connecting the E-Tube wires from the electronic shifters to the rest of the components. It also contains the battery indicator. The junction's LED indicator will display green if the battery is over 50% charged, red if under 50% charged, and flashing red if the battery is almost drained. Mounts just below the step and handlebar junction with an included rubber strap.

Features a three-port E-Tube attachment for use with Dura-Ace Di2 ST-9070 Shifters. Wires are not included. The EW-SD50 rear wire (sold separately) is required to connect SM-EW67 Front Wire/Junction (Junction A) to Rear Junction Box (Junction B; sold separately).
