Firstly, you can't ride the bike off the trainer if you do this. Your comprising the structural integrity of the frame. Secondly, you kill the resale value (Customer: 'What's that dot I see there' ... Reminds me of that famous Seinfeld episode about the sweater and the red dot).

The rear brake cable keeps getting pulled enough that it will cause the brake to drag or even lock up, I want to drill 2 holes in the top tube so I can run a new cable housing from brake lever to brake caliper, can't find much info online so I thought this may be a good source
I already contact Ridley bikes twice and my first respond was " we don't recommend drilling into carbon fiber frame " I submitted the same question again and this time I didn't get any reply
Any input will be greatly appreciated, it looks like a simply job but I worry it may compromise the structure integrity of the frame by drilling holes into the top tube
