With Shimano's simplified and improved front junction box (junction A) for 9070 Dura Ace Di2 and 6870 Ultegra Di2, you now have 5 ports for use with both drop bar and TT shifters simultaneously. The new 9070 unit utilizes a rubber strap that cleanly and aerodynamically fastens underneath the stem. Better still, the 5-port junction box has a charging port that makes it possible to charge both internal and external batteries without having to remove them from the bike.
