Good read - I've been looking at doing a Di2 conversion to my mechanical Norco frame for a while now; thanks for the "how to"

Thanks CulBaire, best of luck with it. Its not all that difficult..if you have a carbon framed Norco, just take a few big deep breaths, lots of measuring, lots of patience and lots of care when drilling! Try and also limit the size and number of holes as I did so as not to compromise the carbon frame integrity too much. I may be talking too cautiously here, but remember this is slightly unchartered territory and invalidates any manufacturers warranty you may have, but the results are worth all the effort if it is done safely!

A silly question. Is the disc mounted on the right side above the bottom bracket a built in chain catcher?

Yep, you got it in one. Had to look twice at it myself when I saw the close up!

I hate to bump an old thread but I am putting together a mechanical foil frame with Di2. The I have managed to get everything in the correct spot but I am struggling with the battery which I will be mounting on the downtube. Currently I have a couple options

1. Run it through the lower cable guide on the exterior of the frame to the battery
2. Drill out the seattube bottle cage lower bolt and run it throug there.
3. Drill a hole through the seattube just below the lower bolt.
4. Drill a hole through the bottom tube as shown in a eariler picture.

It seems like you need to drill a 6mm hole in the frame. Is this an acceptable spot to drill said hole?

Thanks for any advice

Hi Alpine. Happy to give advice based on my own experience.
Im assuming from what you have described that you have run the cable from the front Junction A inside the downtube to connect up with the Junction B and now you are wanting to connect the external battery cable to the internal junction B? If I have that right I would comment as follows on your options:
1. Running it through the lower cable guide below the bottom bracket will do away with drilling holes in your carbon frame but you will then have to tape the cable from there to the battery on to the frame and believe me it is a never ending saga of replacing the tape as it gets dirty and wet, besides it looking awful. I have had to deal with that routing on a Trek Madone and it really did end up a right mess.
2. You could also drill out the seatube bottle cage lower bolt but again you will have to use tape and all the associated problems described above. Besides, you will then only have 1 bottle cage, which might not be a problem for you at present, but think of the onward sale when others may want the option of having 2 bottles for long rides etc.
3 Drilling a hole through the seattube below the lower bolt gives you again the taping problem above.
4. Drilling the hole adjacent to where the battery will lie is the option I would plump for and did on mine. It looks neat, no taping involved and mirrors the same set up as the later internally wired Di2 Foil. It really looks like it was designed that way, in my opinion.

This may sound a bit of an overkill, but please bear in mind as I have stated in my original post, that drilling into a carbon frame will invalidate any potential warranty claims from the manufacturer and although I have had absolutely no problems with stress cracking, or failure of any kind, for over probably 3,000mls of varying conditions of riding, I cannot endorse the drilling into a carbon frame bike. It was my choice to do so knowing all the associated risks by possibly weakening the frame, but I was prepared for that and so far has worked out fine for me, in fact, so much so, I have just converted my Cervelo R5 Di2 from external to internal wiring by drilling a couple of holes in the frame similar to the Scott and again, everything good.

Going back to the actual method of making the holes, I would underline the importance of drilling small and follow up by carefully and slowly, opening out with a fine round file to the 6mm needed to accept the terminal ends. Finish off the hole sides with a small dab of nail varnish to seal the carbon weave from water ingress and potentially delaminating the carbon fibres.

Hope this has been of some use to you in weighing up your options.

Good luck.

No need for any thanks Alpine, I was just hanging around doing nothing as always.

CerveloMad,

I cannot thank you enough for the advice. After I posted I accepted an offer on a new house and have been slammed with moving. I just bought drill bits and files and should be attempting your solution from the above picture this weekend or the next weekend. I bought a 2mm bit and I'll see how the using a file goes and if not I have a 5mm bit as well. I'm going to use my dremel which has an extremly high RPM setting and hopefully that helps smooth it out.

Thanks again!
