The Shimano 2 Ports Junction is a compact, reliable connection hub designed for modern electronic shifting systems such as Shimano Di2. Acting as a central link between your shifters, derailleurs, and main wiring harness, this junction box helps organize and route electronic cables cleanly through your cockpit or frame. Its small, discreet form factor allows it to be tucked neatly under the stem, inside the handlebar, or within the frame, depending on your setup, helping to maintain a clean, professional look on both road and gravel bikes.
Engineered for secure and consistent connections, the Shimano 2 Ports Junction is built to withstand everyday riding conditions, from wet commutes to long training rides. The plug-in ports are designed to hold e-tube wires firmly in place, reducing the risk of intermittent connections or signal loss. Installation is straightforward for anyone familiar with electronic groupsets, and it integrates seamlessly with other Shimano e-tube components. Whether you are upgrading an existing Di2 system or building a new electronic bike from the ground up, this junction is an essential piece for a tidy, dependable wiring layout.
