It serves as a 2-port option for internal E-TUBE wire routing, allowing for charging, battery monitoring, and shift mode switching. By replacing traditional mechanical cables with electrical wires, it eliminates shifting issues caused by contaminants, corrosion, and stretching, providing effortless gear shifts. This junction A is essential for connecting shifters via E-tube wires to the down tube junction wire. It features a battery level indicator and acts as an additional charging point when using an internal battery. It also includes a gear index setup switch for fine-tuning via shifter buttons and boasts reliable, water-resistant connectors. Please note that E-tube EW-SD50 wires are not included.
