Description

Description

The Shimano SM-JC41 Junctionbox makes it possible to connect your Di2 components inside the frame or down tube!

This internal Di2 box from Shimano connects wires from the front and rear derailleurs, the control unit and the battery to the 4-port SM-JC41 junction box installed in the bike frame. However, should you want an external mounting, we recommend the SM-JC40 junction box.

Please note: This junction box fits all Shimano Di2 components except Dura Ace 7970!
