Hi WW

Have any of you tried (or read about) combining the following 11 spd DI2 equipment:

Ultegra Di2 rd
Ultegra Di2 fd
ST-R785 + BR-R785 Hydraulic Disc Brake
Di2 SW-R671 tt shifters
and
XTR Di2 SC-M9050 System Information Display

?
My road bike is currently equipped with Ultegra Di2 and TRP Hy/Rd brakes. I am contemplating on swiching these for the di2 hydraulic ST-R785, adding clip-ons and SW-R671 tt shifters AND the XTR di2 display.

Will all these work together?

That should all work as the display can be used to replace the A junction. The shifters and TT buttons are all fine too.

The only issue is that the display only has 3 ports and you have 5 wires wanting to fit, so either the TT shifters would have to be wired into the shifters under the bar tape (although I can't find an answer for how many ports there are on the shifters) or if you plan on taking the clip-ons off reguarly, you could install a second B junction near the stem and just plug the TT shifters into that to save taking the bar tape up every time.

Of course the simplest option is just to use a 5 port A junction and not worry about what gear you're in :lol:

Every shifter has 3 etube ports, right?

The R785 shifters just have one E-tube port, at least mine does.

But you can use a JC41 to add TT shifters since they have their own "brain".

Adding sprint shifters with R785 requires a lot more work.

there are just plugs in the 785 shifters, you take them out and put the new wire into it.
