Electronic & Hydraulic Shifting (Di2, Ui2, customisations)

If you only have an RD you probably don't need a Junction B if you can run a wire all the way to the front junction (Junc A).

On the other hand, you might need to add a battery into the mix somewhere...

I had a few emails with the guy who did that video in trying to sort out the bar end junction box. Glad I made the effort in the long run but it was an arse trying to get everything just as I wanted it (bought the Pro bars with the holes already in so no drilling/filing for me).

My R8070 shifters have two ports in them so one port in the left goes to the bar-end, one to the RHS and the 2nd port on the RHS is the one that goes into the frame.

I always forget something

But if he had the 2-port shifters the battery could also be wired direct.

They’re 6870 I think

I see.

What does this mean?

Y cable into both shifters and Junc A.
Battery into Left shifter, RD into Right shifter.

Great!

Are all di2 wires the same just different lengths?

In which case @atz I’ll take it!
If @danb doesn’t mind. I don’t like offers, what do you want?

Assuming you don't buy the original Di2 cables from so old 10spd build.

I've got SW r9150 climbing shifters which apparently don't need a 'brain' to connect into ie into the shifters. Someone on slowtwitch just connected directly into a 5 port junction box.

If I've got 9160 bar ends I am wondering if I can connect both using a y cable into the junction (already had junction A's to allow this).

This is for a 1x TT setup btw - and trying to avoid the soldering wire solution previously mentioned..

Yeah, they'd work the same as the TT shifters. You just plug them into a 5-port alongside the normal shifters (or a 3-ports if you don't have normal shifters, ie. TT bike).

Safe. Means I can sell a set of the older TT bar end and brake shifters with a 5 port...anyone interested?

No splits at this stage..

Interested in brake levers and 5 port...

Cool, send me a PM as happy to sell those as a pair.

id be interested in the bar end shifters...

House!

Any hints on how to stop the tab snapping on the eTap battery? Now on about number 6 and getting fed up losing shifting half way through a ride.
Latest issue with Wiggle warranty for a decision on whether they will exchange.

Not had battery tan issue, but about to send my wifli one back for warranty replacement, hopefully.
What have wiggle said?

Still waiting. Sent the email and pictures off this morning. Must admit getting to the point where the reliability of cable would be a temptation.
