1994 Performance R-204 Di2

This was my first road bike, and has been the parts test mule for my other bikes. It originally had a full Shimano RX-100 groupset, and over the years, the parts slowed started getting changed out, until the only original parts left on this bike are the frame, and the seapost binder bolt. This frame has had Shimano 2300, Sora 3500, Ultegra 6500, and Dura-Ace 7700 groupsets on it, and this latest build is a Frankenstein project consisting almost entirely of parts I already had laying around, or purchased from eBay and Craigslist as used or heavily discounted new. I wanted to give Shimano's Di2 system a fair shake, so I sourced the parts, and did an external conversion, and everything works great.

How did you route the wiring for the shifting? Do you have internal cable routing? I have an old steel frame that I want to "electrify" with some Di2 components but am not sure about wire routing

The wire going from the front junction box to the rear junction box follows along the bottom tube. The wire going from the rear derailleur to the rear junction box follows along the chainstay.

Shimano sells adhesive Di2 wire covers designed for external Di2 conversions like this. Alternatively, if you do not have a black or white bike (the colors their wire covers come in), you can always use color-matched adhesive-backed vinyl to camouflage the Di2 cables.

I actually really like this... but I also have a habit of putting new stuff on old frames
