HartGreat Shimano product. I think the 5 port is better for future upgrade when compared to the 3 port.
Paul from SydneyGreat product. Purchased for installation in a 2016 Trek Madone 9 series, which uses a 5 port inside the frame rather than a using a 3 port and an additional junction box near the BB.
SMExcellent product by Shimano and the easiest way to connect up your Di2 on your TT/Tri setup or for those adding clip on aero bars to their Roadie. Highly Recommended. Support and Service from Merlin on Di2 components is excellent.
GraemeOpted for the 5 port junction box to fit TT bar shifters and bull horn shifters. Works like a charm with the rest of my Di2 setup, with effortless accurate shifting. Item arrived quickly and at a great price too. Highly recommended.
Mr St-DenisEasy to install and connect to E-tubes. Configuration is simple.
