    Works great, makes Di2 even cleaner

    • Familiarity: I've used it several times

    This thing deletes the junction box that hangs down under the stem, and makes an already clean front end even cleaner. It comes with mounts for both a bar end and frame port style install. The one thing to note, if you do not have a "di2" specific handlebar, you will have to drill a hole in the drops of your bar in order to get the wires to install the proper way.

    Pretty Lights

    • Familiarity: I've used it several times

    I was most impressed by the pretty lights on this junction box. When I switch syncro shift modes the green and red lights flash simultaneously and no matter the temperature or time of year I can't help but feel a bit of Christmas cheer.

    The actual review: It installs easily with the y split root, allows you to perform adjustments and change syncro shift modes and provides a convenient charging port.
