Reliable Di2 nerve centreReliable kit. Simple to install and connect shifters and battery. 5 port setup permitted a more complex tri bike installation with tri bar and bar end shifters.

For triathlon bikes!This is exactly what ou need for a triathlon bike setup: 2 ports for the brake gear shifters and 2 ports for the remote TT shifters (aero bars).

No issues so far....Currently using the 3 Port version and purchased the 5 Port for a upgrade/rebuild of my Fuji D-6 TT bike. Installing Shimano Ultegra 6870 with Dura Ace bar end shifters and base bar integrated brake and shifter units. Will see how the build goes but installing the 3 Port was pretty much of a breeze.
Hoping to replace my Ultegra Di2 3 port junction box to enable use of bar end shifters. Is this compatible with Ultegra?
Asked by: DGUK
This will be compatible.

Blanking plugs
I'm buying this to future proof my set up, as for now I only need 3 ports, are there any blanking plugs included to keep the two unused ports water tight?
Asked by: nunny1981
Unfortunately wiggleandy got this wrong and after receiving the product they DO indeed have blanking plugs included

R 600/ R785 compatability
Aside from the R 600 climbing shifter itself, is this what I need to make the climbing shifter work with my ST-R785 hydraulic shifters?
Asked by: longwaytim
This will be suitable.

plug and play
Hi, if I was to buy this to replace the 3 port version, would it plug in and work straight away? If not, would I be able to do the initial set up myself by plugging it into my computer or would I need the shop diagnostic tool? Thanks!
Asked by: jackendrick
Plug and play regarding the fitting and then you can programme it using the E-Tube Project tool which can be found here: http://e-tubeproject.shimano.com/
If you have any doubts then please speak to your local bike shop that deals with Di2 parts.
