Di2 11 speed on rim brake steel frame: clever/stupid/goofy solutions?

You actually don't need a B junction. You can solder into a star cfg and heat shrink junction.

All the complications and different versions of wires and connections just makes more people look to the dark side.

The 12 speed idea does have it's appeal, but it also exposes the weakness in my setup.

See, I'm one of those people who got a gravel bike with two wheelsets as their "one bike to rule them all". I also have a commuter/city bike, but we'll just ignore that. Anyway, after riding my very nice carbon gravel bike on all sorts of stuff, I began to miss having a more pure road bike, as well as a classic-ish steel bike. My gravel bike was working so well, I also had no bike wrenching projects. The obvious solution was a steel frame road bike that I could use as a platform for my crazy bike ideas and tinkering platform. i built the first version of this bike up for under $1,000; all mechanical, all external.

Annoyingly, as I looked for inexpensive rim brake parts, I also found inexpensive, modern, current gear. Then I start getting a tickle of, "maybe I just need a modern road frame." The original intent of having a classic style road bike is being smothered by the possibilities and the good deals on modern components.

So, for now, I want to keep the steel, mid-reach-brake frame my north star. I want to be able to put the very nice parts to good use, even if the industry and average consumer thinks that they are outdated.

Otherwise I might just sell a bunck of stuff and but a Roubaix from Blubba.

abandon the idea...buy a different frame that is already setup for di2. try it out and if you really like it then drill the holes in your steel frame.

May the Gods strike you down if your solution is to zip tie it externally

If I may, I would like to present an alternative viewpoint.

I am a very late adopter of electronic shifting. With the help of several generous forum pals here, I was initiated into the world of Di2 less than 2 years ago. I first dipped into 10 speed because most of my bikes at that time were 10 speed mechanical. Like you, I fell in love with Di2 almost immediately for all the same reasons. Within a year or so I converted 3 or 4 other bikes to Di2 and also upgraded to 11 speed.

Now here's the rub. None of my bikes are drilled or prepped for Di2 internal routing.

But that didn't faze or stop me from proceeding forward.

And here's why.

My personal philosophy in life is to live in the here and now, in the present, to enjoy whatever life has to offer instead of waiting for the perfect moment or the future.

I have posted pictures of my bikes set up with di2 here before and gotten quite a few chuckles . They are a complete mess with tape and zip ties everywhere. I don't care.

They have all worked perfectly as intended, from day 1, not so much as a missed shift or accidental discharge. I have traveled with them to France, Australia, Singapore and several other places within the US, on all kinds of road conditions, gravel, road, dusty, wet, mud... you know it, not a peep.

So what's my point?

My bikes may get a C- for aesthetics but functionally they are flawless, for the last two years.

I am glad I didn't wait for the perfect bike to show up or waste a single minute in coming up with some clever/stupid/ goofy solutions.

Start living.

Now.

This is probably the cleanest way to accomplish it.

I felt like such a moron when I bought some Ultegra 12sp Di2 rim brake shifters and kept looking for the "linking" QR codes on them to pair with the RD. As others have mentioned, the 300-series wires are far more svelte and can be spliced in ways that the 50-series stuff couldn't, so at least the wiring harness can be made more "clean". I have a Sachs on order and I'm low key stressin' about whether to ask e-Richie to drill for Di2 or just go with eTap.
