Hoping someone might have some advice.
I use the Ultegra Di2 11 speed shifters on my triathlon bike.
Whilst travelling I crushed a wire and now the right hand base shifter does not work (the rear derailleur).
My local bike store told me I would need a whole new set of base bar shifter/levers to fix this as the wires are embedded into the shifter/levers?
However I saw you sell etubes.
Am I able to just replace the wire?
Also is it possible for someone to just solder the wire?
Thanks
If you know where the bad spot is, its easy to cut out and solder in some new 24 gauge wires. Slip some glue lined heat shrink on each wire and then a bit larger one over the entire section of the new part to ensure full water proofing and you are on your way. I’ve repaired a number of e tube cables that way.
Thanks for that. The e tube cables aren’t expensive, can I just buy one of those and replace or does that not work?
As long as the e-tube cable isn’t crushed at a spot that will impact the shifter, ie right at the port in the shifter, there’s no reason why you should have to replace anything but the crushed cable. Sounds like the shop was trying to sell you some shifters you don’t need.

Thanks for the advice. I think it is more of a lack of knowledge then trying to sell me something as they were happy for me to source the shifters online.
Did you read the bit where he said triathalon bike? The e-tube cable on tt shifters are bonded into the brake lever and can not be unplugged like the road version
That is what I was told but then I saw these
shifters without cables that use etubes. So surely it must be possible…?
I did not realize that. My apologies. I guess he will have to get new shifters if the crushed wire is connected to the shifter.

Or you know, repair it by soldering a new wire as posted above?
Could mean no brake cables? You got 2 choices which is solder wire which I don’t think your lbs will want to do or replace lever

Is that true? That’s dumb considering how prone to damage the wiring is when routed into, through, and out of a bike frame. There’s a chance for chaffing or snagging or breakage when crashing the bike.
You can always verify the wiring using the Shimano Di2 dealer manual:

as posters suggested, you can repair it by soldering. The e-tube cable is not too hard to work with as it is made of two wires as opposed to 5 in the original 7970 Di2.
I crushed the cable coming out of the 6770 extension shifter on my bike and did a soldering job that has held for more than a year. That was my first soldering job ever and wasn’t too hard. There are videos online showing you what you can do, but overall, you know you’ve made a successful solder when you stretch the opposite ends of the soldered cable and it holds. What you need are the following:
-Soldering iron and solder
-A working e-Tube cable (you’ll cut the cable on your shifter before the crimped section and solder that section to the e-Tube cable)
-Something to hold the cables you plan on soldering. Plastic caps of spray bottles work surprisingly well for this
-Ventilation, as you don’t want to breath in heavy chemicals
-Exacto knife to cut and strip the plastic sheath of the cable and wires inside.
-Shrink wrap of different sizes (2 for the wires and 1 for the cable), slipped onto the respective wires and cable before soldering the connection
-A heat gun to heat the shrink wrap. Hair blower may also work, but i haven’t used them
