Drilling carbon frame for Di2

[roger44]

I am upgrading a Bianchi Intenso for DI2 and need to drill cable access for the RD and FD.
I assume I can open out the existing hole for the FD wire to get the FD ewire through from the inside, but to get the ewire through to the RD, I will have to drill the chain stay somewhere along its length.

The is a tiny breather hole in the end, near the drop out, that might be able to get opened out, otherwise I will have to drill and grommet about half way along the chain stay.

Anyone any experience of doing this?

ugly alternative would be to run the ewires along the outside and cable tie them.

I assume I can open out the existing hole

I would never assume anything with carbon . I wouldn't do it but I'm no expert. Consult the professionals.

You'd probably be fine. Note that probably means something entirely different to definitely.

Personally I wouldn't.

 

[Flying Dodo]

Don't do it.

You'll invalidate your frame warranty but if that doesn't worry you....

Give a carbon frame specialist a call if he says he would do the job leave it with him you will have some warranty at least.

But I image the shop would be reluctant to make any modifications to the frame ... I could be wrong.

The only thing that comes to mind is to ask if carefully using a a round needle file instead of a drill would be a safer option?

I have been given a suggestion to cut the end off the e wires, feed them through the existing mechanical wire holes and reconnect the plugs using terminal pics intenrally, that way I only need to open out 2 holes by about 1mm. thats no problem surely, and I can always go back to mechanical set up if I want

Duck tape the wires to the frame. It's invisible.

On second thoughts maybe duck tape dissolves carbon

so many scare sorties about carbon

 

[TheDoctor]

You can stick things to carbon to your heart's content. You're actually sticking them to the surface layer of resin.
I'd be very wary of drilling carbon.

Just to digress. Is it Duck tape or Duct tape?
Apparently both .It started off as the former when in military use in the Vietnam war and morphed into Duck tape for air-conditioning ducts and other applications in later civilian use, according to a video from Simple history I received recently.

Duck tape was the original. The name has been mispronounced and bastardised, and then reused itself over the decades. That's what I once read in The Dandy.

Is the origin of this tape American? I think they commonly use the term Duct tape. As mentioned- ventilation ducts.
