drilling hole in carbon frame
This is one of those questions where if you have to ask &quot;should I do this?&quot;, the answer is &quot;no&quot;. Carbon frames need to be specially reinforced (during manufacturing) in the areas that drilling takes place see, for example, this discussion, and you could create stress concentration points or otherwise compromise the integrity of your frame.
The words &quot;catastrophic frame failure&quot; are not ones that you want to hear, particularly from your hospital bed.
