I found myself with nice Caad8 frame, optimo and US made. I'm thinking about running internal DI2 cables with seat post battery. Anyone drilled aluminum frame before for this aim? Do you think that the frame get damage? If you had past experience, where is the ideal location for the head tube area drill?
I assembled the bike in our shop couple of weeks back and from memory the hole was drilled in the non-drive side part of the toptube.
I can post a detailed photo of the wiring and such tomorrow if you want?
not that the link is likely to dissuade you from getting on with the job, but there's folks that've been there already to learn from eh.
I'm still at least 10 years off electronic gearing.
Bigger holes even than you would need for the new e-tube wiring. I choose the downtube between the cable stops and then right in front of the bottom bracket.
Tapped on the frame to find the thickest parts. Used a bunch of tape to protect the paint and drilled.
The aluminum drills easily. I actually used a carbide Dremel bit to the open the holes to the oval shape recommended by Shimano. No cracks so far, not even in the paint. Probably 700 or 800 miles on the frame so far.
The only thing I fear from is safety, I'm afraid that the frame collapse under my legs.

I dont really care about warranty..i use this frame for city bike this days. I have supersix as main bike. Is it possible for you to upload some pictures of your drilled bike?
