SHIMANO's SM-EW90-B 5-port Junction A mounts neatly to the bike stem and connects with E-TUBE wires from DI2 shifters, accessory shifters, and the downtube junction wire. The SM-EW90 junction box features an integrated battery level indicator, charging port, and gear index setup switch.
Why would you need the Shimano E-Tube Di2 5-Port A-Junction Box? Well, because it's two better than the 3-Port A-Junction Box. It's also really important if you want to have shifters on both your base bar and aero bars on your TT bike and you want them BOTH to work. It also features a plug on the side for charging an internal battery if you have one, so that's cool. Isn't technology great?!
